Gigatron Hackers

The Usenet group alt.folkore.computers appears still active, they even started a Zilog Z80 vs. MOS 6502 thread a couple of day ago :shock:. Luckily there is also a more interesting thread about the history of BASIC. This YouTube video is an interesting watch, about a time well before both Bill's BAS...

Thanks for posting! Every picture of a newly completed built makes us blush...

As said, the software needs improvement to deal with longer key presses. My ambition is that Snake, Racer and the setting of the clock in Mandelbrot should all work in this setup. I don't know if that is all realistic, and it very likely requires total assimilation of the PS2keyboard module. So this...

I see such strange things in one of my posting as well. I have no idea, it seems the preview function alters results? In one case I got a "free", untraceable, image included...

We just installed the forum software from a package and didn't look back. Don't know how to fix it.

I played with the DigiSpark about two years ago. IMG_3642.jpg I also bricked one or two by destroying their boot loader I believe, and I couldn't figure out how to bring them back to life. I find it easier now to program the bare ATtiny85. There is more than one way to skin a cat. I'm toying with th...

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. It looks I broke our "compiler" at some point towards making it independent. This program doesn't load from the standard address $0200 but at $0600...

These are my current thoughts. It pays to think this through while at some point building blocks will also just emerge. There is room for multiple developments. I just found back some of our notes of just one year ago, and can only smile of what we were concerned with back then. One point of view i...

Got it working now. Even 8 MHz is too slow for the old code and all bits to the Gigatron were shifted by one position. The Arduino ran at 16 MHz and is fast enough. I solved it by rearranging the bit-banging code and now it looks fine. I hope I didn't break the rest of the functionality of LoaderTes...

I spent some time today on the ATtiny85 route. It is not stable yet, but there is clearly signal processing going on. In fact, on the scope it looks all good, but for some reason the wrong keys get through most of the time. It shouldn't be a major leap from here. I'm using the PS2keyboard module for...
