Someone recently asked me a few questions about design, which got me thinking about writing a series of posts for this website.
I hope to encourage anyone who has considered designing their own retro computer add-on, or indeed a whole system, to have a go. Getting that first professional looking PCB in the post is very rewarding and is relatively cheap.

Z180 motherboard
Currently in development is a Z180 motherboard with RC2014 compatible expansion sockets.
Further details here.
RomWBW for SC111
Wayne Warthen’s RomWBW is now available for SC111, Z180 CPU module for RC2014.
Getting Started
You are probably reading this because the idea of making a computer with retro technology sounds fun. Perhaps you are my age and have fond memories of learning BASIC on an early home computer, or perhaps you’re a product of the mobile phone era and want to experience the early days of micro-electronics.
This article discusses some of the options available.

I launched my first kit for the Z80Bus today.
This card is a Z80 processor card which can also be used as a Single Board Computer (SBC). Full details here.
The kit is available on Tindie.
I’ll make the PCB available on its own as soon as I have spare boards.
Z180 for RC2014
I’ve now released my Z180 module set for RC2014, consisting of a Z180 CPU module and a Z180 memory module.
