My Texas Instruments TI-99/4A Home Computer Page

My Early Experiences with the TI-99/4A:

The Texas Instruments TI-99/4A Home Computer is my first and truest retrocomputing love. We had a TI-99/4A in the house when I was very young in the early 1980s, and I have many fond memories of the TI-99/4A from those days:

• Educational games (i.e., cartridges or "command modules") for the TI-99/4A such as Early Learning Fun, Beginning Grammar, Alien Addition, Dragon Mix, etc.
• Learning to program in TI BASIC using various resources such as the Beginner's BASIC and User's Reference Guide manuals included with the TI-99/4A, and the 10-part Teach Yourself BASIC series of programs on cassette. I recently completed video/emulation run-throughs of these resources, which you can see in the following YouTube playlists:
  • TI-99/4A Beginner's BASIC, Chapter's 1–5 (YouTube Playlist)
  • TI-99/4A User's Reference Guide Type-In Programs (YouTube Playlist)
  • TI-99/4A: Learning BASIC (Teach Yourself BASIC), Chapters 1–10 (YouTube Playlist)
• A cute little asterisk-shooting program, Shooting Star, that my dad wrote for me in TI BASIC and saved on cassette. Sadly the cassette that this program was stored on has been lost, but I have slowly been working on my own recreation (and improved version) of Shooting Star in TI Extended BASIC. I'll post the completed program here after I've completed it; stay tuned!
• Having great fun playing various games for the TI-99/4A, such as Alpiner, Car Wars, Centipede, Hangman, Ms. Pac-Man, Pole Position, TI Invaders, Video Chess, ZeroZap, etc.
• Messing around with the TI-99/4A Speech Synthesizer and getting it to say all kinds of crazy things!
• Composing music on the TI-99/4A via the Music Maker cartridge / command module.
• Typing in various TI BASIC type-in programs from computer books such as 101 Programming Tips & Tricks for the Texas Instruments TI-99/4A Home Computer by Len Turner. I recently completed a video/emulation run-through of all 101 programs from this book, which you can see in the follolwing YouTube playlist:

My List of Essential TI-99/4A Links:

My Massive List of TI-99/4A Type-In Programs (Work in Progress):

I have been working on compiling a massive spreadsheet of TI BASIC and TI Extended BASIC type in-programs from computer magazines and TI users group newsletters from the late 1970s, throughout the 1980s, and into the early 1990s. This is a work in progress, but the list already contains over 2,000 programs with a link to each program listing in the original publication/source. I am actively adding to this list regularly, so be sure to bookmark the following link and check back regularly!
