The First Step in Building our TMS9900 Homebrew!

Описание: I’ve been excited about this one for a long time! The TI-99/4A seems like a run-of-the-mill home computer, but lurking inside beats the heart of a 16-bit minicomputer. It’s time we unleash the beast, letting the TMS9900 stretch its legs and run like it was meant to. But, this is going to be a long journey and this is just the first step.
