Things I've Built

Econet Expansion Board

The result of a little scope creep during upgrades to the EcoPort, this card contains a replica of the original Acorn Econet Card, a modern on-board econet clock generator, a 6522 with two additional user ports, and space for a daughter board.

EcoSound

A PCB that sits on the internal Econet header of a BBC Master and mounts a 6522 that controls a YM2149F sound chip. Audio is routed out via the (otherwise unused) econet port.

EcoPort

6502 SBC

A simple homebrew 6502 system for playing around with.
