Re: Gigatron on an FPGA

Hi, this was an evaluation board that was designed by my team to prove out a new (back then) design many years ago and is not available commercially. I was happy to rescue it from the dumpster and find it new life as a Gigatron. Everyone on the team I showed it to thought it was very cool playing Te...

Re: at67 emulator

I haven't figured out much the controls.

Re: at67 emulator

Thanks MCD for compiling it. This might be more a question for at76. It looks like the emulator emulates PS2 keyboard entry, but does it also work with the save/CTRL-F3 mechanism to save BASIC programs? I tried and while save seems to have done something, when I tried CTRL-F3, it didn't look like it...
