I was able to build my gigatron and works, it turns on. The main issue I am having is that that I cannot move the cursor. Since the kit did not come with the original famicom controller, I first used a serial Sega controller and then I used an NES controller but I still could not move the cursor. A...

That's pretty impressive, cool!

Brings back memories of the first 1-bit sound in MSX games :)

Re: Gigatron Similar machine

Maybe this is something for hackaday.io? Over there, you'll have a bigger audience, bigger than just the Gigatron-audience. Also, if if takes off, you'd already have everything neatly in one place.

Re: tutorial about programming ATTINY85 with Arduino Nano

Sorry, I missed the Arduino Nano bit. I've always used a TL866 programmer to program the ATtiny and set the fuses.
How you'd set the fuses using an Arduino Nano I don't know.

Re: tutorial about programming ATTINY85 with Arduino Nano

That's needed to get it to run at 8MHz. It needs to be done only once.

Create a file fuses.txt with:
fuses_lo = 0x00e2
fuses_hi = 0x00df
lock_byte = 0x00ff

Then set them:
minipro -p attiny85 -w fuses.txt -c config

Re: whole board with 74LS

See https://forum.gigatron.io/viewtopic.php?f=4&t=258

You'll probably want to stick with a 74HCT04 and a 74HC595.
