Retro Computing

IMPORTANT NOTE – If you have a TI-99/4A Home Computer equipped with Stuart’s Internet Browser, then come have a look at the TI version of Wagner’s TechTalk! You can find us using his browser at

The following are the latest TI-99/4A / Retro Computing videos from Wagner’s TechTalk. Much more is planned for this year. Enjoy!

FinalGROM 99: Run most all TI-99/4A Cartridges from a single cartridge! +DEMO Retro and NEW GAMES!

This amazing cartridge by Ralph Benzinger allows you to easily install TI-99/4A .BIN files to an SD card for use by the TI-99/4A. This allows you to have a single cartridge that can run/play most any application/game on a stock TI-99/4A console.

In this video, we’ll launch a few applications and try out several games and even the infamous “Don’t mess with Texas” demo! So sit back, grab your favorite beverage and let’s have some fun with FinalGROM 99 and the TI/99/4A!

Browsing the Internet on a TI-99/4A Home Computer with Stuart’s Browser and TIPI

We’ll check out Stuart’s Browser for the TI-99/4A and TIPI! This new version of his browser supports the networking features of the TIPI to allow you to browse the internet from a computer that is nearly 40 years old. We’ll have some fun checking out a TI-capable version of the Wagner’s TechTalk website and visit some additional sites designed specifically for the TI.

Dragon’s Lair for the TI-99/4A Home Computer- NEW in 2019! FULL Play-through in practice mode

In this video, we’ll un-box #59 of the less than 100 original Dragon’s Lair games (by HarmlessLion) for the TI-99/4A Home Computer! There are a small number of released cartridges into the wild and we will play the full game that you may remember from the 1983 laser disc classic.

To assist me in completing the game, we’ll take advantage of the practice mode where no lives can be lost. Keep in mind, any pause you see during the game-play is only the game waiting on me to press the correct move while in practice mode. There is no lag during an actual game.

You can read more about the history on this project from the author’s blog.
The original AtariAge thread announcing the game’s imminent availability may be found here.

Dragon’s Lair for the TI-99/4a was announced/released on Jan 31st 2019. My copy was #59 and was received on March 14th 2019.

TIPI: Raspberry Pi connected to a 40 YEAR OLD TI-99/4A Computer!-Gaming/Chat/Mouse/Disk/Telnet+

This is a comprehensive video of the newly released TIPI (Raspberry Pi solution for the TI-99/4a) available at and created by JediMatt/ElectricLab. While it’s a little long (~42 min.) it will help you through the setup and demonstration of many of the capabilities available.

This video is ideal for new TIPI users as well as someone contemplating getting one for their own Ultimate Retro TI-99/4A setup.

This video covers the following topics

  • Brief Intro. of the TIPI
  • Assembly of the 32k Sidecar + TIPI
  • New Case for the above (Awesome design and perfect fit!)
  • Creating the TIPI Disk Image for the RPi
  • How to configure the TIPI to your WiFi Network
  • How to use the Built-in Telnet client to connect to your RPi (can also be used to connect to BBS’s)
  • How to use TI-Artist with a Mouse + TIPI
  • Demonstration of programs including: Chatti, Chess and (my favorite) SNEK!
  • How to access your TIPI via a UNC Path and copy files
  • How to use the TIPI Web Administrator to create folders and new TI Files
  • Demonstration of loading your TI Files (from the TIPI) on the TI-99/4a
  • Where to purchase a TIPI + 32k Sidecar and also the 3D Printed case!

TI-99/4A Home Computer Introduction / History 

Introduction to the TI 99/4a Home Computer which was launched in 1981. It was one of the first (if not “the” first), 16-bit microprocessors available for the home. This video takes you back to the early days with a little bit of my own memories of this fantastic Home Computer!


The nanoPEB is a modern alternative to the larger Peripheral Expansion System released in the early 1980’s. While the nanoPEB doesn’t allow adding expansion cards, it has most everything most TI users could appreciate. (*Note – You may also find the TIPI an interesting alternative to the PEB)

Preparing and Managing the nanoPEB CF Card with TI99DIR

If your CF card is in need of an upgrade (or is missing/damaged), you’ll need to know how to create a new image for the nanoPEB. You may also want to know how to easily copy new TI disk images to your CF volumes, this video will show you how easy it is to do all of this!

TI-99/4A – AWESOME UPGRADES: Video converters, TI99Sim, FlashRom99 and more!

we’ll take a look at the type of adapters you would need to replace the TI Monitor with a VGA/HDMI Monitor. We’ll also look at the TI99Sim running on a Raspberry Pi 3b which can nicely emulate the TI on a RPi3. We’ll also consolidate a large collection of TI cartridges into a single FlashRom99 cart.

TI-99/4A running Assembly code in stock TI Basic (emulated in this video)

This code was loaded into the classic 99 emulator by copy/paste directly into TI-Basic. Then run, it was amazing!

Harry Wilhelm developed the method for running assembly in BASIC. He essentially overruns certain memory locations to force assembly code into memory

The code was not written by me, but can be found here.

Special thanks to the TI 99ers facebook page for posting this and many more great TI resources!
