Gigatron Hackers

Very nice! The parts drawer looks very familiar to me :) . In my first design I thought I need a dedicated bit to show that a key is pressed and the keycode is valid. But after my positive experience with your little terminal program I think I don't need to waste the bit any more. I can use it as a ...

Thanks! Did you know about the Digispark? A nice little PCB with USB plug and Attiny85 16.5MHz. That could be the perfect interface board to connect USB or PS2 to the Gigatron. There are also dozens of cheap clones around. The only downside it's a bit tricky to get the tools into the Arduino IDE. As...

Very nice and minimalistic solution. Maybe a little bit brute force. ;) Until I am get into GCL I tried to compile and transfer your little Terminal App called Main.gcl. Compiling worked well but transfer doesn't. All other GCLs in gigatron-rom-master I tried in the same environment worked well. May...

Both solutions work stable. Thanks for the fast integration. Yes, the Arduino Micro has a different USB behavior to the Uno because there is no dedicated USB controller. Automatic (Software) Reset and Bootloader Initiation Rather than requiring a physical press of the reset button before an upload, ...

YES! - It works really well with no modification at the original Terminal.ino test program. I thought I get, at least, problems with key bouncing. Ok there are not real keys yet, but that's the next thing to come.

After some long hours setting up my iMac (El Capitan), Python and an Ardunio Micro to communicate with the Gigatron i decided to write some of my experiences. Maybe I can help someone to getting this faster. :lol: Gigatron: ======== 1. Load the Gigatron tools from Github: https://github.com/kervinck...

More than one attachment in a reply gives strange results. If you add a second attachment the first preview works normally. But submit or second preview - removes the first attachment in the list - places the second under the inline code of the first - gives an error at the second inline code A: Mot...

I agree that two more shift registers is not nice. The one on the board is already a little cheater. After all, software could easily sample the game controller bits during vertical pulse. The 74HC595 is rather complex because it has 16 flip-flops and a tri-state buffer. We're effectively not using...

Attachment 2:
(Shift Bit is still in non ASCII compatible position D6 here.)

It works... so far. No magic smoke! GigaKey_Proto_1.jpg - I swaped the 74165 for the 4014 shift register. Now I don't need the inverter that causes to much delay. - The wired AND stops row counting as long as a key is pressed. YES - Now I can say the hardware part is working because I can measure al...
