Re: Gigatron Soundcard
I have no musical talent. I just wanted to see if the Gigatron could control a sound chip. I thought the SN76489 was the simplest option. Since the Gigatron can only write ports, not read them. I hadn't gotten my board to work yet and had almost forgotten about it. I wasn't aware that the SN76489 wa...

Re: New size coding contest "ZX Spectrum effect"
This is outside of the competition here. I just wanted to point out another idea. I tried using the v6502 CPU. The actual program is 19 bytes without crashing. To activate the v6502 CPU on the Gigatron, another 12 bytes are required for the official route. The entire GT1 file is 40 bytes. Maybe ther...

Re: gtmine [game]
The 32 version does without two image lines at the top in order to have enough memory.
the game itself is no different. only slight visual differences.

Re: gtmine [game]
gtmine was my first attempt at writing a game in glcc. After it was running, I didn't bother with the code anymore. I just tested it on my Gigatron and it works. But I loaded it via spi of the 128k expansion. lb3361 explained it above. thanks for the tip. The latest version of the game should be fou...

Re: New Gigatron in Russia
I think it could just be the monitor/tv or quartz?
I have already tested Gigatrons on various monitors and TVs. If they synced badly, then the picture was shifted. I've never had a picture like this before, it's too big on all sides.
Why ROMv4? But it has nothing to do with the monitor.

Re: 10MHz, 12.5MHz and Beyond!
I played something with the Gigasaur today. Since the Gigasaur uses the 74F00 family, I used a 50 MHz oscillator. This means that the Gigatron clone runs at 12.5 MHz. To get an image I used the ROMv3y. Compared to the ROMv3, the Mandelbrot is about 4 times faster. However, it is still significantly ...

Re: Gigatron 512k and more
I wanted to solder. So I built a few extensions.
If you're interested, I'll give you an extension for €40 plus shipping from Germany.
All successfully tested.

Re: KiCAD v7.0 compliance
For finishing at JLCPCB I always used the original Gerber files. (https://gigatron.io/?p=2230) I never had any problems with it. Opening the KiCad files in a newer version only makes sense if you want to change the layout of the PCB. But that amounts to a new Gigatron clone. There is already the Gig...
