I’ve just put together a couple of PCB sets for sale on Tindie.
3-slot Backplane
Want a really small backplane for your RC2014?
Breakout module
Here’s my take on a signal breakout module designed to aid prototyping of RC2014 modules on solderless breadboards.
Z80 SIO/2+CTC module
Another slot saving module. This time combining Z80 SIO/2 and Z80 CTC, for serial and counter/timer functions on one board.
Modular Backplanes (Update)
I’ve updated the documentation for some of the modular backplanes.
Modular Backplanes
I’ve been working on a system of modular backplane sections.
Z80 Processor module
Slot saving module up and running.
Z80 PIO module
Here’s the third module in my set of Z80 peripheral chip implementations.
Z80 SIO/2 module
Here’s the second module in my set of Z80 peripheral chip implementations.
Z80 CTC module
My first PCB in a very long time!
