Web article Nine



by Charles Good Lima Ohio User Group

Hank Mishkoff worked on a lot of projects for TI between 1978 and 1983 relating to the 99/4, 99/4A and 99/8. As an independent contractor he wrote the code for some early TI education command modules, wrote the music for some modules (he is a musician), and wrote some of the 99/8 documentation. He also was an employee of Tronics, which is a company that sold 99/4A coputers through multiple layers of distributors much like Amway home care products are sold today. In addition Hank worked in 1983 for Looking Glass Software and was involved in the creation of some of the never released ET command modules. What follows is compiled from a telephone interview and (mostly) from a number of separate internet email messages sent between Hank Mishkoff and Charles Good in late September and early October 1995. You certainly meet the most interesting people on the internet!

CG-- Tell me about some of the early work you did that relates to the TI Home Computer

HM-- I worked for TI as a programmer on the 99/4 in 1978, and then again doing documentation (and some programming) from 1980-1982. (Oh yeah, I'm also a musician; a lot of the music on TI's programs -- especially the early ones -- was mine.) For about a year after that, I worked with a company called Tronics, which sold the TI Home Computer on a multi-level basis. Following that, I did contract work on various TI products for years. I'm not an engineer, so I may not have the kind of info you're looking for; but I was involved with TI Home Computer products for quite a while, and I'd be happy to share my reminiscences with you any time you're interested.

CG-- The following is quoted from the June 1980 issue of FORTUNE magazine and describes the situation at TI in 1979 as TI considered developing an advanced version of the 99/4 to be called the 99/7. Any comments on this?

"Internal competition ultimately put the kibosh on the 99/7. TI's digital systems group, which is based in Austin and sells minicomputers to small businesses, argued that it should control development of the 99/7 because the machine was designed for small businesses. Besides, the 99/7 was so powerful and inexpensive that it would have cannibalized the low end of the minicomputer line.

The squabble went all the way up to top management, which decided at the last minute to cancel the 99/7 introduction and transfer the project to Austin. There, the "not invented here" syndrome took over. Austin engineers started questioning the new product's technical and economic feasibility, and within six months, most of the project staff had left for other jobs in TI. Looking back on all this, an allumnus concludes, "They threw away the two pieces of gold and kept the lump of coal.""

HM-- Wow, this section is incredibly accurate -- I remember quite well when all of this happened.

CG-- Did you have anything to do with the 99/8 project?

HM-- Wow, does *that* bring back memories. I wrote the manual for that sucker; I didn't know that *any* of them were ever actually produced. I just went back and dug up an old invoice dated 7/7/83, in which I billed TI for my expenses in shipping them the final copy of the TI-99/8 manual counter-to-counter air freight (they must have wanted it *real* fast). If I remember correctly, I had worked on the manual all night (hey, I was a *lot* younger then), then drove to D/FW Airport in the wee hours of the morning to ship the manual to Lubbock. I seem to recall that the product was killed shortly after that; I doubt that the manual was actually printed.

Another nostalgia note: My invoice says that I shipped the manual to Monte Williams; Monte has since moved to Dallas, and now heads up Micrografx' documentation group.

CG-- I have the 99/8 book you wrote! I have rough, not quite ready for printing, "Final Draft 09/15/83" of the "TI-99/8, Book 2, Programmer's Guide for the Computer 99/8". Much of it looks it was printed on a line printer. It's about 300 pages. I can send it to you if you are interested, no charge.

HM-- I am definitely interested, thanks! That sounds like my book. It's probably slightly revised, since my records show that I shipped them *my* final draft in July.

CG-- I don't have a 99/8 but I know some people who do. One friend has a hex bus disk drive, an armadillo interface, and a whole bunch of special memory expansion cards that only work with his 99/8.

HM-- Well, I'm more amazed all the time. The very concept that you would personally know more than one person who has a 99/8 is stunning. Do you have any idea of how they got them? (Or why they would want them?) Did they work for TI?

CG-- Did you do any work on the 99/2? I have one of these, complete with a built in hexbus interface that can use all the little hexbus peripherals that TI sold, and some they never sold. I also have a "Wafertape digital tape drive", serial number 0000007. I can understand why TI never sold the things. Mine doesn't work at all reliably.

HM-- I don't think so. Let me take a minute here and search through some old invoices...

Nope, lots of charges for the 99/8, nothing for the 99/2. Did the 99/2 precede the 99/8? It seems to me that they provided me with a copy (possibly a draft) of the 99/2 manual, and I used it as the basis for the 99/8 manual. Maybe not.

CG-- In the Spring 1988 Triton catalog NUMBER BOWLING is listed for $11.95 as cartridge #1030. It is one of the modules shown on the video tape I am sending you. Did you work on Number Bowling?

HM-- I think I might have written Number Bowling, but I wouldn't swear to it. I worked on a few of the Scott Foresman programs, but I sure can't remember which ones right now.

CG-- On December 15, 1994 Thomas Hartsig left a message on the comp.sys.ti internet newsgroup. He was commenting on discussions of recent sales and purchases by newsgroup readers of TI educational modules. "I wrote Addition and Subtraction 1 back in 1981. I had no idea people were still using these cartridges." Were you involved in that project?

HM-- I always thought that *I* "wrote" it, but I guess that depends on how you define "wrote." Tom designed the module and "wrote" the specification; I "wrote" every line of code that went into that module.

CG-- So why is Thomas Hartsig's name prominantly displayed on the title screen of Addition & Subtraction 1 and your name is found nowhere, not even in the documentation. Why are you given no credit?

HM-- Here's a funny story for you (well, *I* think it's funny, anyway)...

All of the programmers were miffed when we saw that Scott Foresman wanted to put Tom's name on the title page of Addition and Subtraction 1. Not that we had anything against Tom (we had never met him, for one thing; and for another, his contract with SF *required* that they give him onscreen credit), but we had all been developing programs for the Home Computer for years, and not once had any of us been given that kind of visibility. We weren't angry, but we were annoyed.

When I had completed a first pass of the program, I flew up to Chicago to show it to the folks at SF; I knew that Tom was going to be there also. (I think that was the first -- and possibly the only -- time that I met him.)

Just as a joke -- and to exact some small measure of satisfaction -- I changed the onscreen credit from Tom's name to mine, mostly to see how he would react (and, I suppose, in some obscure way, to make a point).

So I'm in the room with Tom and two folks from SF (Bob and Dee), and I fire up the program, and up pops the title screen with my name on it. I keep a perfectly straight face, like nothing's going on. Bob looks real surprised for a second, then he smiles, and I think he's going to laugh, but he covers his face with his hand for a second, and then he's got a straight face, too.

And Tom, who is staring directly at the screen, doesn't react at all! I even find some excuse to keep the title screen up there for a few extra seconds to make sure he sees it, but there's no reaction. I figure that he's missed it, maybe he's been looking at the esthetics and hasn't noticed the switch. Bummer.

After a while, Bob and I leave to go talk about something else, leaving Tom alone with Dee. Later, Dee tells me that the second I left the room, Tom turned to her and said, worriedly, "I didn't know that *Hank's* name was going to be on the title screen!" Dee, who had figured out what I was doing, said something non-committal like, "I'll have to review that with Hank to see what's going on." I got a *tremendous* feeling of satisfaction after that; all I had been trying to do was to tweak Tom a little bit, and it had worked. Life is full of little victories!

CG-- Did you do the music at the beginning of the Music Maker module? You can hear this music near the end of the video I am sending you. It is, I think, a Beethoven sonata.

HM-- It's possible; I'd have to hear it to be sure. Actually, the main reason that TI hired me was because of my background as a musician; my programming training and experience were pretty weak at the time. When I went to Lubbock for my interview in early 1978, they were in a position where they were making this revolutionary computer with three voices, and yet they had nobody on their staff with any musical ability.

I hadn't mentioned my muscial background on my resume, because it didnd't seem relevent to a programming job. And TI couldn't tell me anything about the product(or even admit that they were working on a home computer) because the product hadn't been announced! Finally, in my very last intreview of the day, someone asked my about the two-year hole in my resume. When I mentioned that I had been playing in a band, his eyes lit up -- although I had no idea why, and he couldn't tell me. Weird.

When I first started on the job, my first assignment was the Home Budget module; any experimenting with music was on my own time. I remember that I programmed the Minute Waltz to play in less than a minute -- it sounded terrible that fast, but it was a lot of fun. I also did a Bach two-part invention that was one of my favorite piano pieces; that may be what they later used on Music Maker.

Then I started doing little bits and pieces for the Grammar module, which everybody liked so much that they decided to actually pay me for creating music (as long as I got my "real" work done on time!).

The piece I'm most proud of is a three-part piece I wrote for the Demo module. Unfortunatley, they chopped it up and only used pieces of it. I've recently entered the entire piece into MIDI format; if you have some way to play MIDI, I can send you the file as an attachment, if you're interested.

CG-- Sure, send me the Demo module music in MIDI format.

webmaster here- this MID file is on the main TI resource page on this web site.
HM-- Ok, here is the demo module music. I've attached three slightly different arrangements. I would have only sent you the best one, but I'm not at home, and I have no way to play them, and I can't remember which is which.

By the way, here's a funny story about that music, which was written for the Demo module. I left TI before the computer hit the market, and I was real excited when it finally began to show up in stores -- especially because a lot of retailers, having no idea of what else to do with it, just left the Demo module running in an "endless loop."

One day, I stopped into a computer store with some friends of mine, hoping to show off the computer -- and my music. They had the Demo program running, but the sound was turned off! I asked a salesman if they ever turned the sound up. "Yeah," he said. "When we're bad salespeople, they turn the sound on and make us stand next to the computer!" I had never realized that my wonderful music could get on your nerves after you'd heard it maybe 500 times...

HM-- Here's a long shot for you: When TI pulled the plug on Home Computer division, I was in the middle of writing a program that I believe was planned to be put into a "Command Module." I was writing the program as a subcontractor; the contractor was a company named Looking Glass. The program had to do with the adventures of ET; TI had licensed the character from Speilberg. Looking Glass had contracted to create 2 or 3 ET adventures; I don't remember the name of the one I was working on. I assume that, when the project went under, TI would have had a current copy of the code, and someone could have burned it into some EPROM's (the programs were pretty far along). Have you ever seen or heard of any program that might fit that description?

CG-- Which ones? Of those I know about one was just called "ET" and was a frogger like game where ET had to cross the highway, river, etc. to get to his space ship at the top of the screen.

HM-- Nope, that one doesn't even sound familiar.

CG-- The other, and maybe the one you worked on, is called "ET at Sea". It is a world geography game. ET has to move around a map of the world visiting cities and getting clues to the location of his space ship.

HM-- Now we're getting somewhere -- but that still isn't mine. Mine was called "ET's Adventures on Land" -- which I *never* would have remembered, not in a zillion years, if you hadn't jogged my memory with the At Sea title. If my memory is accurate after all these years, the "At Sea" program was created by a programmer who worked for Looking Glass; his first name was Pete, but I can't remember his last name.

(I vaguely remember that it was some kind of long Polish-sounding name.) His wife was also a programmer; she worked for a company in Richardson (a Dallas suburb) that did a couple of TI games, including one called HenHouse or something like that.

CG-- I have a video tape of these two modules, and other never released official 99/4A module software that I will be glad to copy and send you.

HM-- I would *love* to see that! The memory overload might prove to be fatal, but it would be worth it!

CG-- I have heard of "ET and his adventures on land" and always thought it was the frogger type game I described. Nobody that I have ever heard of has seen the "adventures on land" software.

HM-- I don't believe I was as far along on it as Pete was on the Sea module when work was discontinued. As I recall, I had programmed in all the little animals and animated them and given them paths to walk on, but the game didn't actually *do* anything when it was abondoned. You could move the animals around, but that was it. My guess is that nobody saved it because it was so incomplete.

Looking Glass Software (the company that had the contract for the ET games) was run by Gary and Mary Schenck (since then, they've been divorced, remarried, and divorced again), with whom I still speak every once in a while; if I remember, I'll ask them if they still have a copy of ET/Land, such as it was. Gary lives in KC (he's an art director for Hallmark), and I'm going to be visiting a client next week who has an office just down the street from his house; I think I'll give him a call.


I was right in the middle of writing this note, thinking about what the chances were that Gary might have any idea where any of my old work might be, when it hit me that I might have some old stuff lying around -- and guess what I found???

I opened up one of my old diskette cases (this is starting to sound like the discovery of King Tut's tomb), and the diskette on top was labelled (in my handwriting) "E/A," which I assume means Editor/Assembler. The only project in which I ever used the Editor Assembler was the ET game, so I figured that I might have hit paydirt -- although I did work on the manual for that product, so the diskette might contain documentation, rather than code...

But here's what the labels on the other disks say:
ET LAND ("GROM7" crossed out) CODE FILES

Also, there's a sheet of paper with what looks like some coding equates for animals, homes, and food (12 of each); I'm thinking that maybe you were supposed to get each animal to its home and feed it (?).

Anyway, I'd like to mail this stuff to you, if you're interested and if you think you might be able to make some sense out of it (and if you think there's half a chance that the diskettes are still readable). Would you promise me to let me know what's on it before you make it public and let me "withdraw" some of the stuff if it turns out not to have anything to do with the Home Computer (like if I included a list of my ex-girlfriends and their phone #s...)?

(Charles Good's added note:-- Hank did indeed mail these disks to me, along with the "ET and his Adventures on Land" programming notebook containg original graph paper drawings and notes of all the graphics in the game, as well as extensive dated notes concerning the conception and development of all the Looking Glass Software ET series of command modules.

There were three planned modules called Land, Sea, and Air. The notebook contains little information on the Air game beyond its general concept. The Sea game exists in the Lima software library as GROM files that can be run with a gram device, as well as a slightly buggy version that works from extended basic. None of these three ET games are the same as the frogger type ET command module game, which was not a Looking Glass Software project.

The disks are TI DOS in SSSD format and contain lots of GPL source and object code for the Land game. There are no phone numbers of girl friends. The code is incomplete and the game is not functional. At Hank's request, I copied the disks (some were duplicates) and made a xerox copy of the development notebook, then returned all the originals to him.)

CG-- Do I have your permission to give copies of your disks and notebook to others interested in the 99/4A?

HM-- Absolutely, although I must tell you that I have no idea whether or not I have any legal right to give you that permission. I suspect that Looking Glass (which doesn't exist any more) or TI may own the rights to the material. Practically speaking, however, I have a hard time imagining that anyone would care, at this late date, as I can't see that any of that stuff could possibly have even the slightest commercial value.

CG-- The Looking Glass notebook you sent me has several pages that are headed "Conceptual development for TI/SDA education modules.." What does "SDA" stand for? I have a never released TI module that says "Music SDA" on its title screen. It is the regular Music Maker module with extra code that allows you to get printouts of assembly source code, GPL source code, and Basic CALL SOUND statements that will produce the music you enter into the module. I have always wondered about the meaning of "SDA" in this module's title screen.

HM-- I don't have a clue what SDA means -- although you'd think I'd know, seeing as how it's in my notebook. I've forwarded your question to Paul Urbanus, the creator of Parsec, who's the only one of the TI Home Computer programmers that I keep in touch with; I'll let you know if his memory is any better than mine.

CG-- I am today mailing book rate a VHS video tape with 6 hours of viewing. Included are many of the never released modules such as the ET stuff, a bunch of Bill Cosby commercials and pep talks designed for 99/4 and /4A retailers, and the official TI Retail Training video. There is lots of footage of the 99/4 (no A).

HM-- That sounds great. I remember seeing Cosby at a CES show in Chacago; TI had rented a ballroom as a hospitality suite, and he was posing for pictures with retailers. There was quite a long line, as I recall, of people waiting to be in some pix with Cos.

CG-- I have a Tronics cassette tape set.

HM-- Which one? Do you mean audiocassette or program cassette? I was involved in both projects, so you may have some of my work after all.

CG-- Both audio and program cassettes. The audio tape has your voice on it! It was apparently made in 1982 and features you introducing yourself by name. The "Sights and Sounds" program tape credits you as one of the authors of this TI BASIC software

CG-- From a newsletter article I wrote a couple of years ago: "TRONICS was created by Mike Wilcox and Dave Guardanapo to sell 99/4A's using a pyramid system of distributors and subdistributors, similar to the way AMWAY home care products are sold today." Any comments?

HM-- Actually, Tronics was the brainchild of Jody Black, who was a Braniff pilot (a captain, actually) at the time. Pilots make a lot of money (he was pulling in 6 figures at the time, as I recall) and have a lot of free time on their hands (since they work only one out of every three days). Like firemen (who are in a similar situation, but with less money), pilots tend to get into other businesses on the side. And since he traveled so widely (and worked with a lot of other people who travelled a lot, too), Tronics spread quickly all around the country. I knew Dave, and Mike's name sounds familiar, and they may have been successful Tronic distributors (for a while, anyway), but they were *not* involved in its founding.

Tronics always had trouble acquiring enough credit. Thus they had trouble keeping inventory and were very slow in delivering product to their distributors. This trouble delivering goods that had been paid for doomed the project. Eventually Tronics was sold. It went through several sets of owners. The last guys to own the company milked it dry, taking all incoming cash and delivering nothing. I had some involvement in advising a bankruptcy judge on the distribution of the company's remaining assets.

CG-- From my newsletter article: "Apparently TI knew about and approved of TRONICS pyramid sales scheme."

HM-- They knew about it, but were always a little leery of it. Actually, Tronics was an offical TI distributor; they couldn't have done what they did withough being able to purchase products at distributor prices. It took Jody a long time to convince TI to let him do what he did; many people were surprised that TI went for it at all. And Tronics was a "multi-level" company, not a pyramid scheme -- the differences are many and can be subtle, the main one being that pyramids are generally illegal.

by Bill Gaskill

I would venture a guess that most people who have owned a TI-99 for more than a couple of years have run across the name John Phillips before. He is a near legend in the TI-99/4A cartridge and assembly language programming community and can claim authorship, co-authorship or significant involvement in over a dozen cartridge programs produced for the 99/4A, not to mention numerous articles written about the inner workings of the 4A's architecture.

Phillips will be 32 years old this year (1993) but he was only 21 when he was hired by Texas Instruments in 1982 right after graduating from Illinois State University. He started his career with TI in Dallas doing COBAL programming for business applications but it took him only 6 months to get a requested transfer to Lubbock where the "real" action was. John had purchased a 99/4 during his senior year in college and was already familiar with the Home Computer's architecture and he had wanted to program video games since purchasing his first cartridge, which was Munchman. Phillips didn't know TMS9900 assembly language but it didn't take him long to learn it.

His first project at Lubbock was Moonmine, followed by Hopper, which he co-authored with Michael Archulata. Hopper was followed by Word Radar, which he wrote in 2 weeks, for Developmental Learning Materials (DLM), the firm started by Bill Maxwell and Jerry Chaffin.

After completing Word Radar TI sent Phillips to Japan where he met with several companies who were being recruited to write software for the 99/4A. Following his return from Japan he became involved in almost every piece of software that was slated for production or that was actually produced for the 99/4A. When TI announced the end of the Home Computer Division Phillips was offered several incentives to stay at TI but turned them all down because none involved work with the 99/4A. Instead, he and fellow employee Michael Archuleta went to work for DLM, which had continued to work on products for the TI-99/4A even though it was no longer being produced.

In December 1983 John Phillips announced to the TI Community that he was available to any User Group for seminars, demonstrations and question and answer sessions related to the TI-99/4A. He would travel to virtually any location if the User Group would pay round trip airfare from Dallas, Texas plus lodging? While he could only make himself available on weekends, it was a pretty generous offer.

Both Phillips and Archuleta eventually left DLM (probably because the work there dried up too) and started their own firm in February 1984 called Video Magic. Video Magic also came to an end in too short a time, I suspect because it was becoming painfully obvious that one could not make a living trying to write software for the 99/4A.

At Texas Instruments Michael Archuleta was responsible for the 99/4A Technical Hotline and for 99/4A software quality assurance. Phillips was a third-party software development consultant and programmer in the education/entertainment section of the Consumer Products Division. Both men would get together again in 1986 to collaborate on the 4A FLYER game cartridge that was commissioned by Triton Products. To date, that is the last time we've heard from the John Phillips/Michael Archulata team.

Archuleta and Phillips were involved in, or responsible for such TI-99 favorites as:

ANGLER DANGLER - Phillips worked on this project as the debugger of the final code, but the project never reached completion before the bailout so Angler Dangler was never officially released. It does exist in GRAM file format however, so it probably was not too far from being a real product when someone at TI made the decision to pull the plug. If you look at the October 23, 1983 IUG price list you will see Angler Dangler listed as being available.

BEYOND PARSEC - This cartridge, which Bill Moseid's DataBiotics firm released for the 99/4A during the third quarter of 1988, started life in early 1984 as one of two game cartridges John Phillips was writing for CorComp's new CCI-99/64 (aka Phoenix) computer. The other game was Star Wars. Both efforts came to a screaching halt however, when TI objected to the use of the Parsec name, and George Lucas' company apparently objected to the use of the trademarked Star Wars name. The Star Wars code must have actually been finished at the time though, because I have the game on disk as a GPL file. It was ultimately renamed Star Trap and released in cartridge form by Exceltec in 1985 and then by DataBiotics during the third quarter of 1988.

BEYOND SPACE - This is a John Phillips creation that was completed in May 1984, but not released until the first quarter of 1985 when Exceltec/Sunware marketed it. It was picked up by Unisource Electronics for their catalog/encyclopedia but pretty much floundered and then just disappeared. It has never resurfaced since both Unisource and Sunware went out of business in 1986.

The game involved two players with each having a ship of equal firing power. The area in space where the two ships confront each other is littered with asteroids which may be moved by firing the ship's laser. The object of the game was to push asteriods into your opponent's space ship to crush and destroy it. The only review I've ever seen written on the program claimed that its speed was too fast to play the game very long, so that may be why it has slipped into oblivion?

BURGERTIME - Phillips provided the final debugging for Burgertime.

D STATION - This John Phillips creation has the distinction of being the only program ever released by the International 99/4 User Group on the Romox ECPC cartridge. You may recall that during the fourth quarter of 1983, Charles LaFara promised "a library" of programs from the IUG on the Romox ECPC (Edge Connector Programmable Cartridge). D Station was just the first, but it also turned out to be the last.

When the IUG ECPC library failed Exceltec (aka Sunware) picked up the program and marketed it for a short time in 1985. Triton finally introduced D Station in their Fall 1988 catalog along with a brand new D Station II game, also written by John Phillips.

D STATION II - See D Station.

FACEMAKER - Phillips collaborated with Intersoft's Jerry Spacek on this project. Spacek you may recall wrote Defend the Cities, which was the first commercial Mini-Memory assembly language game ever written. In the Facemaker project Spacek translated Spinnaker's source code to TMS9900 assembly language and Phillips ported it to cartridge format.

HOPPER - Michael Archuleta and John Phillips co-wrote Hopper, which was the only cartridge developed entirely on the TI-99/4A Home Computer, using the Editor/Assembler cartridge for all of the programming. All of the other TI-99 cartridge software programs were developed on a TI Mini, not the 99/4 or 4A.

JAWBREAKER II - Phillips converted the original Sierra On-Line source code to TI-99/4A code.

MINI MEMORY'S LINE-BY-LINE ASSEMBLER - Phillips claims responsibility for its development, but I am not sure exactly what that means.

MOONMINE - Programmed by John Phillips from a design by Bob Hendren. You may remember that Hendren was also the project engineer behind Parsec and the person who recruited Aubree Anderson to do the voice for the Parsec game. PETER PAN'S SPACE ODYSSEY - Phillips and Archuleta collaborated on this program while employed at DLM. It was never officially released but is available as a GRAM file that can be run from P-Gram, Gramulator or the GramKracker.

SLYMOIDS - Slymoids was written by James R. Von Ehr II. The cartridge conversion was accomplished by John Phillips.

STAR TRAP - See Beyond Parsec.

SUPER DEMON ATTACK - Phillips worked on this project, but I have no information on the specific contributions he made to its completion other than possible debugging of the final code. I do know that he actually worked on Demon Attack, not Super Demon Attack, but they are probably the same project with the actual marketed product just having a slightly different name.

THE GREAT WORD RACE- John Phillips authored.

TREASURE ISLAND - Phillips provided the final debugging for this game cartridge, which had apparently become stalled by a bug that no one could find.

WORD RADAR - John Phillips authored.
