The full book Getting Started with the Texas Instruments TI99/4A by Stephen Shaw online.

This site has a number of articles about the TI99/4A (some quite long)- this link will take you to a descriptive menu.

An official photograph (32k) - taken for publicity purposes showing the console (keyboard) and (not connected) behind it the Expansion Box (for 32k ram, disk controller and 90k 5.25" disk drive). To the left a pair of joysticks. To the right a speech synthesiser and an accoustic modem (modem never sold in the UK). Photo by Jim Childress of Lubbock, Texas.

A very early module for the TI99/4a, used in stores, was the Demonstration Module. A short tune was written for this by Hank (Henry C) Mishkoff (in his own time) and Hank has supplied two Midi arrangements of the tune, TI1.MID and TI2.MID - under 3k each. If you do not have .MID files associated with a .MID player, save the files and play them later. Hank left TI before the computer was marketed. Hank has a web site too. One reader wrote to tell me these two files were identical- nope, I've printed out the music. The TUNE is the same but the instruments differ, the odd note is slightly different and one has an added countermelody. Perhaps you need a musical ear to detect the changes Hank made!

Jim Muller began working with LOGO while public relations manager for Texas Instruments in 1979. After introducing TI LOGO, the first commercial Logo package, in April 1981, Muller organised the first Logo users group, The Young Peoples Logo Association. TI Logo is available for the TI emulators. In 1997 Jim had a book published The Great Logo Adventure(here as a 3.6 megabyte zipped download), complete with CD Rom for PC and Mac, supporting MSW Logo.

One of the educational modules for the TI99/4A was PLATO, a mini-PLATO from CDC, which used a huge number of data disks to teach almost anything. The PLATO courseware system is still in use despite several changes of ownership and technology.

Rich Polivka has been a leading supporter of the TI99/4A on the Internet and has a large content rich web site at 99er.net. The site has huge resources and is well worth visiting.

A long standing supporter of the TI99/4a was Jim Peterson of Columbus, Ohio. Jim produced a monthly column, reprinted in virtually every user group newsletter, for many years. Jim died some years ago, however in his memory here are two issues presented in TXT format in the original 28 columns that Jim used, to fit 3 columns per A4 page.

Visit CaDD Electronics for details of the PC99 TI99/4a Emulator for the PC.
To run PC99 in its native DOS operating system you may need to get a copy of FreeDOS, one flavour of which runs from a floppy with no hard disk install or partitioning.

A very strongly recommended product from CaDD, supporting their PC99 product is a very handsomely full CD-ROM (The Cyc) for just US$25 inclusive, which includes a lot of printed material in PDF format, and many programs (thousands) to run with the PC99 emulator including the entire Tigercub and Amnion software libraries. A lot of work has gone into this and it is excellent value. Even if you choose not to run PC99 (for copyright reasons relating to the licence Mike has, you have to buy a copy of PC99 in order to buy the Cyc), the Cyc still has very much material of use including for example all the TI modules in PC99 format and 9900 assembly language primers. (Want to see a photo of a TI99/7?).

My TI99/4 and 4A led me to meet and correspond with many people over the years, sometimes over many years. Some of these have inevitably but sadly died. Here in the UK especially missed are R Matthews of TX Software, who died much too young and so early in the TI's lifetime that few will know of him. He was a first class programmer- sufficient to lead a Cornish software pirate to offer me Mr Matthew's programs as his own. Ian Martin of Timeless Software published several fine programs and also died much too young. I corresponded for many years with Americans Ray Kazmer, Jim Peterson, and Guy Stefan Romano, sadly missed. Thomas Weithoffer lived just long enough to release a TI99 version of the language Pilot.
