Description

Proto card for my HBC-56 8-bit homebrew computer. 

https://github.com/visrealm/hbc-56

 

I've used this to build the following cards:

  • 6502 CPU module
  • 3-way clock (based on James Sharman's design)
  • RAM/ROM module
  • Character/graphics LCD module
  • TMS9918A graphics module
  • Dual AY-3-8910 sound module

 

Schematics for all modules in the github repo.
