TI resources on this site, with links to a publicity photo of the
computer, some music in .MID format originally composed for a very
early TI module, and a memorial sample of the monthly columns of the
late Jim Peterson, a longtime supporter
of the TI99/4a computer. also a review of PC99 and some programs for

Computer Conservation Society, including the first stored
programmable computer, the SSEM, now rebuilt and working twice a week
in Manchester. Another early British computer, Colossus (predating
Eniac), was hard wired for one task- dealing with Enigma
messages- lovely description of how Enigma worked and was deciphered.
Creative Computing was one of the computing magazines I first read

web plus the three books "The Best Of...". Read computing

I have discovered and now use sdlBasic which exists in a 2012 build for win32 and deb and in a 2007 build as an rpm. You can see some of my programs at Stephen's sdlBasic routines.
There remain some excellent programs for DOS which cannot be run in Windows XP, or for a
smaller number, in Dosbox under Linux or Windows XP. To run in a native DOS
operating system you may need to get a copy of FreeDOS or Balder, one
flavour of which runs from a floppy with no hard disk install or partitioning.

My favorite 32 bit Windows media browser is the
free Irfanview. Huge list of supported formats of images, animations
and sounds; includes the special overview.pcd file format. Irfanview also has some
image editing options and scanner (Twain) input. It is quite small,
with plug ins in a separate zip file- you can delete any you don't
need after unzipping.
Although written for Windows, I was surprised to find many parts of Irfanview (up to version 4.33) work fine in Linux using Wine (up to vn 1.1.9). I recommend NOT using the Associate file type option on a Linux box. There may obviously be problems with files that use external viewers which are
less receptive to Wine but I am happily using Photoshop 8BF filters with it and also the OCR plugin. Irfanview makes viewing and editing jpeg image metadata really easy (EXIF, and IPTC). Details of using Irfanview on Linux. (Linux native programs GIMP, fotoxx and gthumb are of course excellent - and exiftool is the Linux metadata reader/writer but console only).

Mirrorservice.org is a UK based
ftp mirror site with files from many sites. The new hardware is now installed (2013) and the mirrors updated. Apart from Opera (browser) it seems to be almost entirely Linux / Unix software. The old dos / windows material has gone. There is no search facility. This is the mirror service offered by the University of Kent and will be very fast for Uni students connected via Janet.
