My Gigatron build
Posted: 11 Jul 2021, 19:05
Here are some pictures of my Gigatron TTL build I just finished this weekend.
When the Gigatron first came out, I found it vaguely interesting, watched a few youtube videos, but never intended to build one.
But then 2 years ago I ended up with a BasicEngine kit, built that, and then this year I also built a clone Jupiter ACE (Cees Meijer's version), and then recently a friend gifted/traded me a Gigatron PCB, and it's bad form to waste an empty PCB![Smile :)](./images/smilies/icon_e_smile.gif)
All the components were sourced locally (Cape Town). Here are the specs of my board (mostly based on which components I had already):
Clock 6.5 MHz (extra from the Jupiter ACE build).
Most IC's are 74LS. The clock "conditioning" IC (U1) is 74HCT04 and also using 74HCT377s.
Power consumption: 430mA ?
Surprisingly it worked first time when I first powered it up! However after a few minutes it locked up and now only runs for a few seconds before crashing.
