Usually, i just put here game consoles or systems that are usually not emulated from the first generation of video games, but this time it is a game system from the 4th generation (well...game system is pretty stretching it) called the Tandy/Memorex VIS (Video Information System) MD-2500.
To make a story short, this "wanna-be" educational system is now rare to find and sought after even if i would classify it as "Worst Game System EVER!!" but this is still part of the video game history and is also a great part about computer history since it has a "Modular Windows" for an operating system. Actually, it has a Windows 3.1 modified inside two EPROMS.
The BIOS of this system has two EPROMS labeled P513BK0B and P513BK1B which are 16-BIT (512K each in size) 27C240, and now these two EPROMS are now dumped but still need to be verified to see if both are good dumps. And if they are good then we need to wait that someone makes a driver for the MAME (MESS) to be finally preserved (Hey, even if i think it's the worst game system ever, it's still need to be preserved for historical purpose).
Here's a few pictures (and guts):
And pictures of the controller:

I will post soon scans of the VIS manual and Compton manual, until then take care folks! =)
