Gigatron Hackers

Very nice! In the meanwhile I have managed to get the SD card file transfer finally working. You can check out the code in my fork of the git repo: https://github.com/DerTyp321/gigatron-rom/ Turns out the issue I was having with that was a stack overflow, due to the Atmega32U4 only having 2K of SRAM...

After some consideration your solution seems to be the better option, since its more consistent with the PS/2 code and doesn't require reworking the serial code. Only downside is that while a button is held down nothing else works. But that was already the case with the PS/2 keyboard and shouldn't a...

The code for the Gigatron->PC Serial link containing the call to waitVSync() is commented out, so game controller data ist sent every VSync Pulse. Should have probably deleted that part to make it more clear. As I mentioned in my last post this serial functionality is something I want to bring back ...

What I did to get the Game Controller passthrough working again is basically just manually pulsing the game controllers latch and clock pin while reading from the data pin, and then sending the controller state to the Gigatron every Frame (except when a key of the keyboard is pressed). I had to redu...

Ill post my code later today, when I'm back home.
The images from the last post should be attached.

After some more prototyping with a Pro Micro Board and messing around with the BabelFish code, I have now managed to get the game controller and the PS/2 keyboard to work simultaneously. I had to temporarily disable serial output from the Gigatron but it shouldn't be too hard to get that working aga...

Thanks for the offer! This project is also an excuse for me to learn EDA Tools. I'll see how far I can get with KiCad by myself and might get back to you.

Hi Monsonite, while I would prefer to have a one board solution, your suggestion sounds like a great first step, to get the software and IO side sorted out. I might actually do both since this is mostly an exercise for myself anyway. I would probably use a Pro Micro instead of an UNO then for the sm...

Thanks all very much for your feedback! I want one, too! Have you considered offering them for sale? I didn't expect that so soon :). I'll get it working first, and then I might consider it. From what I see, VCC comes from the Gigatron. The USB's VCC comes from the controller chip, and that chip get...

Hello all, I am in the process of building an IO board for my Gigatron, basically a more advanced "Pluggy McPlugface", thats supposed to tap the full potential of BabelFish. The board will connect to the Game Controller port on the Gigatron and feature PS/2 keyboard input, game controller ...
