Gigatron Hackers

Very nice!

Maybe a bit overcautious, but whatever works for you is fine. And in the end the satisfaction of having a Gigatron build by yourself working on first try is all that matters.

Very nice!

It's very addictive (but I don't need help ).

I was inspired by all the clocks being posted, so I thought I'd add my own to this thread; the timing code for this clock also originated from this thread. Very nice, looks good! I had already noted that it makes sense to add 2 seconds to S as entered by the user, which is about the time it takes f...

In case someone should want to attempt something similar: I recently did try to use a NodeMCU (ESP8266) instead of an Arduino, it started promising but in the end I decided it was not worth the effort. It's not an AVR compatible board and unable to handle AVR-specific registers such as PORTx and PIN...

This is the (for now) final code. I'm now down to a less than 1 second deviation per day, and that's good enough for me ;) 'graph display with clock '(hr:min) using 59.98Hz 'counter. UnREM lines 175 'and 235 to see seconds, 'adjust I (1/100 sec/min) 'and J (1/100 sec/hour) 'for clock finetuning. 10 ...

Hi Marcel, Thanks for that. I've already rewritten my code using peek(14) and am now checking its accuracy. I had reckoned one complete cycle on address 14 takes 258 / 59.98 = 4.268 seconds, and use that number to check if a minute has passed. Should work equally well. But I'm undecided yet which wa...

Hi, Not an original idea, as I've seen it done before by someone on Youtube, but my Gigatron begged to be modded in a similar fashion. As pretty as it already is, I couldn't help adding more bling: https://vault.crouze.com/Other/2020/MDX-200103-P20-OC21180-x.jpg https://vault.crouze.com/Other/2020/M...

A Happy New Year, and a good New Decennium too for all. And happy hacking too

I did the 64k upgrade today, very easy with the above guide (thanks!). I usually don't necrobump "old" topics, but in this case it might be useful for others who are thinking of doing the same. I did all wiring inside the 32-pin socket, and used an angled pin header for A15. I think the re...

Nice pictures!

I can't help but look at the "diode farm" now and then as well

Cheers,
