RaspTI: Convert a Vintage Computer (TI-99/4A) into a RaspPi Workstation
Matthew Epler created an Instructable documenting his project of turning a TI-99 console into a Raspberry Pi workstation. On the one hand, I hate to see a TI pulled apart and used only for the shell. On the other hand, I find the project interesting because in part 1, Matthew shows how to interface the TI keyboard to the microcontroller. Actually, I\\\'m not sure if the other parts of this project are going to be finished since part 1 looks like it may be at least 11 months old.

Here\\\'s the link:

Running The TI-99/4a In Your Web Browser (with MESS)
A group working on a port of MESS " (Multi Emulator Super System) has a beta version available that definitely worked for me using the Chrome browser. Others may be functional as well. The Javascript MESS project site allows you to try out different supported systems. The TI-99/4a is one of those systems, and you are able to choose the cartridge that you want to run from the drop-down list at the top of the screen. You then start the system up by pressing the space bar.

New Version of the Win994a Simulator - 3.010
Cory Burr has released a new version of his TI-99/4a simulator for Windows. This update consists mostly of some technical modifications including the X cpu opcode being modified so that it functions correctly, the preferences dialog now has a fast 16bit access 32K Extended Memory option, and the assembler application has been updated. Download on the Win994a Downloads Page.

New Version of V9T9 Emulator
Many years ago, Ed Swartz released the final version of his TI-99/4A emulator, V9T9. That version ran from the command line in DOS or in Windows with a front end. A month or so ago, Ed released his latest public version. It's written in Java, and can therefore be run on many different machines. The interface is very polished and even supports drag and drop cartridges! You can download the new version from Ed's website at If you're interested in the old version, you can still download it from this site in the download database.

FC5025 5.25" Floppy Controller
I purchased a FC5025 controller from Device Side Data, and have been using it to convert all of my old TI-99/4A 5.25 floppy disks over to Win994a format.

The FC5025 connects between your 5.25" drive and your PC via USB. The included software can read several vintage computer formats including the TI-99/4A. You then use it to make a disk image that is compatible with the V9T9 emulator (which is the same as the Win994a disk image- just change the extension to 'TIDisk').

The whole process is pretty seamless and takes only few seconds per disk. It's the easiest way I've found to convert them.

I have begun converting my collection of disks, and uploading them to the Win994a disk section of the download database. Check back for new additions.
