Retrocomputing, hardware and embedded software projects

These are some recent projects that I (Shiela) have been working on, related to my interests in retro computing and music rather than PeacockMedia's usual area of desktop apps and web crawling.

They are mostly designed around the Raspberry Pi Pico / RP2020 with custom software in C.



RP2040 board with HDMI, sorry, DVI socket, all GPIO broken out and DIP styling. And it's black!

Developed as part of my TMSEMU project, this will be useful in other projects.



Pocket-sized theremin-like MIDI instrument

Played with gestures in the air like a theremin and can output MIDI over USB, MIDI over TRS, audio at line or headphone level.



Classic SID sounds with MIDI input

A synthesizer - MIDI in, two modern SID replacements, audio out.


USB keyboard interface

For Minstrel 4th

This is a USB keyboard interface for the Minstrel 4th Jupiter Ace clone from Tynemouth Software.


Emulated TMS9918A with DVI

A graphics module for RC2014 with emulated TMS9918A, DVI output and additional functionality.

This is again designed specifically for the RC2014 Z80 computer and other machines with the RC2014 bus.



An RC2014-based MSX-compatible computer
