Prototype RetroShield’s for 1802, 8031, 8085 arrived!

2019/07/03

Well, look what I got. 3 new RetroShields for 1802, 8031, and 8085. Work is busy lately but I will work on these as fast as possible.

I want to study the memory access waveforms, find monitor codes and write support for peripherals. Lots of fun :)

For 1802, I want to emulate COSMAC Elf. So good luck to me :)

PS: The green mask on 8085 PCB was a mistake. Oh well, that’s why we build prototypes first :)
