I2C Modules

I now have circuit boards for the first batch of I2C modules.

Discount Code

I’ve been playing around with Tindie’s discount voucher mechanism and have (I hope) created a code for 10% off everything in my store. The code is “C442589B”. Just enter this at checkout to get a 10% discount. The code is valid for orders placed during February 2021.

The Road Ahead

A few people have asked me recently where I’m headed with my designs. So here’s my current thinking.

SC140 Released

SC140 is a Z180 SBC built on a Z50Bus card.

SC141 Released

SC141 is a 13-slot RC2014 compatible modular backplane.

SC142 Released

SC142 is a power supply module designed for the RC2014 bus.

SC137 Released

SC137 is an I2C bus master module designed for the RC2014 bus.

SC138 Released

SC138 is an I2C memory card designed primarily for use with SC126 and SC137.

2020 Reviewed

2020 has been another good year for the homebrew retro computer community, but not such a good year for freedom and health!

Example I2C code

I have written some more I2C example code. This code is compatible with SC126 and SC137. More details here.
