UK magazines for users of the TI-99/4a Home Computer
What UK magazines were there about the TI99/4a?
Personal Computer News was a weekly magazine which had some serious coverage of the TI99/4a, including two articles by me covering efficient programming on the slow limited memory machine, and a technical article on how programs were stored internally and how a program could overwrite itself (articles dated 6/5/83 and 7/9/83). Plus a letter on the use of logical operators on the TI99/4a. There is also part of a review of my book from an Australian edition of Your Computer.
TIdings was the magazine of the original UK TI99/4A User Group (TI Home) originated by Paul Dicks - articles appear below.
TI*MES was a user group magazine originally produced by Clive Scally which was the effective descendant of TI Home and ran and ran for many years - articles to be found below. From issue 16 Clive handed the running over to voluntary committee management. TI Home Computer Users Club was a commercial thin magazine arranged by Texas Instruments for UK TI99/4A users, to take over from TI HOME which was being swamped. First magazine. It was produced by a PR company and its fate was sealed when TI immediately stopped selling the computer. whtech.com has issues 1 to 4 in pdf format - issue 1 as Autumn 1983-1, issue 2 as 1984 Winter, Issue 3 twice, as Autumn 1983-2 and Autumn 1984, and Issue 4 as Winter 1985.
I have issue 5 of the TIHCUC magazine which was very thin- three pages of adverts and five of "editorial". It did say the mailing list was being passed to someone in Glasgow who would continue support- but nothing was ever heard of them. I can't OCR it but have made it available as an ODT (Open Document Text- but it contains embedded images not text) file or separate jpg images.
TI-USER was a small magazine for UK TI99/4a users published by a retailer (Galaxy) in Maidstone.
The first issue of TI User || TI-user issue two | |
TI-User Issue 3
I also have issues 4 and 5 but the print copy is not good enough for me to use here.
TI-LINES was a privately produced magazine for UK TI99/4A users produced by Peter Brooks then in Oxford.
From 1984: Issue 3 of TI-Lines | |
Issue 4 of TI-Lines
As I can't contact Peter for consent to republish here, and have more work to OCR than I can manage anyway! I will leave it at two sample copies, the absence of more should not be considered in any way negatively.
Parco Magazine was another retailer produced magazine from Parco of Honiton. Issue One was the one and only joint venture magazine with Albert Visser of Holland (with contents mostly from Holland) but as things didn't work out, from issue two it was a production of Parco.
Originating in the English language this time, Issue 2 of Parco Magazine, most of the content was fairly unreadable listings, which I have had to omit- I was never able to read them. I do have additional copies, but I am not able to OCR them.
Finally- the United States Air Force was protecting us, and provided a good market for US products such as the TI99/4a. From one US air base in England came the magazine of the
East Anglia Region 99ers.
whtech.com have 15 issues from 1987-88.
Many of the copies I have are not scannable, but one article by Colin Hinson from the October/November 1988 issues is worth typing in -
now you can read in detail about the TI disk peripheral system, and . I am not able to contact the publishers for consent to add more material so this sample will have to suffice. Some of their copies would not OCR but there was much interesting material. I also have a very incomplete set. read how the 4a stored files on floppy disks
TIdings from TIhome TIdings and TI*MES both initially contained a considerable amount of technical and programming information and continue to be goldmines for users of the emulators.
TIdings 1981 First ever three issues of the UK User Group Newsletter TIdings, from way back in 1981.
TIdings July 1981- issue 4. Large article on Boolean operators and various news.
TIdings September 1981- issue 5 with the first news of the hidden Basic commands Call A and Call D.
TIdings December 1981 - issue 6 full of historic hints and tips for owners of the TI99/4a computer (and now, its emulations).
Summary of TIdings 7 to 9 (1982) - to cut down the irrelevant material, I'll move on to quoting relevant historic and technical matters from later issues. The ninth issue was Volume 2 Number 3.
Rambles from TIdings issue 10, August 1982 including A program that rewrites itself,
Using a Personal Record Keeping database with TI Basic, Using a PRK datafile to hold array values, Graphics Mode 3 and Range and accuracy of Call Sound
Rambles from TIdings Issues 11 and 12 October and December 1982 including hints on program debugging.
TIdings March 1983, (Volume 3 Number 1) - almost all of the March 1983 issue of TIdings
split into five parts:
Part One includes Babbling Brooks, Beginners Basic (If Then Else) and an introduction to 9900 Assembly Language.
Part Two includes Programming For-Next Loops and is mostly written by Peter Brooks.
Part Three Mostly Rambles by Stephen Shaw, includes the differences between the 99/4 and the 99/4a, saving data (not programs) to cassette and to minimemory; using sprites in TI Basic; a program that writes itself; reviews of Mindstorms and Cubic Circular; and first words on the 99/2 and the CC-40 (which did not make it to market).
Part Four |
whtech.com has TIdings in pdf format for the issues of Oct 1982, December 1982 and March 1983.
whtech.com has TI*MES in pdf format for Issue 1 (Summer 1983), issue 7 (Winter 1984), issue 9 (Summer 1985), and issue 10 (Autumn 1985).
Rambles first appeared in TIdings and then transferred to TI*MES from issue 2, and was then in almost every issue for many years. Issues without Rambles were typically due to delays in the delivery of previous editions leading to too short a time to submit fresh material, or later, changes in the editor (and where to send copy) that I was not aware of. Below this paragraph will be the Rambles part of TI*MES, although some parts may be omitted due to being utterly irrelevant, or incapable of OCRing. I may have to include sections from other parts of TI*MES for Rambles to make sense. Rambles from TI*MES by Stephen Shaw
