Gigatron Hackers

Hi, this is the third Gigatron-TTL I've built. The previous two are fully functional and I use sometimes to play a little, upload stuffs by the SD card etc., but I still had a couple to build, including this one - that's the first one I bought as diy kit from an eBay seller. Since this is the only o...

mine has a strange behavior, sometimes it doesn't respond, sometimes you press down and it goes left, etc. Could it depend by the slightly different crystal frequency (I'm using a 6.4 MHz crystal) ? Its' a crappy controller, indeed. Oh, well, I could always convert it into a Commodore 64 / Atari Joy...

hi guys, I bought a couple of cheap controllers on Aliexpress: https://pt.aliexpress.com/item/32919127872.html They work, some way, but with some issues: i.e. when I play snake, the arrow buttons work fine for a while and then begin to fail (and my snake hit the wall...). I opened them to take a loo...

That makes more sense, something probably can be done for TinyBasic, but it would have to be completely barebones, (i.e. no browser, flat file system etc). yes, the simple SAVE and LOAD commands would be fine and enough. About the browser: what about the Commodore system for the disk browser, a LOA...

Paper tape anyone? Something interesting on this side in the Altair-Duino group, take a look: https://groups.google.com/g/altair-duino/c/gTXT3jPUEQU The worst part is to build a puncher for tape roll from the scratch... it would also be nice to use common and available paper roll, like paper roll f...

Marcel wrote most of the firmware and I am just a contributor like everyone else. Yep, I said you wrote most of the CONTRIB software/firmware; and that's true, you're definitely one of the most active programmers for the Gigatron, your contribution was (and is) crucial for the Gigatron community. P...

you wrote most of the contrib software/firmware for the Gigatron, including the SDcard browser so of course you're one of the best guy to ask: do you think is it hard to develop some support for a virtual disk on the SD card (I mean: mount a virtual disk and use it from inside Gigatron) ?

Recently I got a Pluggy Reloaded and I mounted it on my first Gigatron using the NO_ROM option (I will use the ROM option on the 2nd Gigatron as soon as the missing 74hct will arrive from Aliexpress and eBay). As usual at67 did an awesome work on that, not to load the programs is like a breeze. I wa...

You would pretty much have to duplicate what Norgate did with Pluggy Reloaded and his SD Card reader, as you surmised Arduino's run out of storage very quickly when using external libraries, i.e. I doubt you could fit the SD and floppy libraries in a typical device. yep, definitely the SD card read...

hi all, I was looking at the David Hansel's project (https://github.com/dhansel/ArduinoFDC) about to drive a floppy disk from an Arduino (various flavors) and I was wondering if there's a way to hook up a floppy disk drive to the Gigatron. Since the David's project uses the same pins used by Babelfi...
