RETRAC

digital logic

Similar projects worth following

RETRAC is a relay computer.  Nothing is built yet.  It's still only sketches. 

Tentative design:

  • 12 bit accumulator machine
  • stored program
  • relay latch, relay/capacitor RAM
  • diode matrix + switch ROM
  • SPST reed relays
  • interrupt support


The architecture is a simple memory-accumulator machine, with just enough features, like indirect addressing and return address linking, to support structured programming.

I have always wanted to build a relay processor but the number of relays and cost has kept me from doing that. I tried to make my own very rough relays but it would take a lifetime to make enough of them unless 3D printed is a option. Do not give up on your idea, I would like to see this happen for you :-)
