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!
Alphanumeric LCD
Every system needs a small Liquid Crystal Display, right!
Tom’s SBC
I’ve built Tom Szolyga’s SBC version C.
Small Computer 101
A prototype Small Computer has been built and works as expected.
It has 128k bytes of FLASH and 128k bytes of RAM. A simple paging system allows access to all of the memory. A serial port is included for connection to a terminal. Expansion is available through an RC2014 bus connector.
Small Computer 002
This is a slight upgrade on design 001.
The Small Computer design 002 is a minimal Z80 system.
It has 128k bytes of FLASH and 128k bytes of RAM. A simple paging system allows access to all of the memory. A serial port is included for connection to a terminal. Expansion is available through an RC2014 bus connector.
