BBC Master 128 – Raspberry Pi Co-processor
I found about about the ability to add a co-processor to the BBC Master 128 when I came across this level shifter on eBay and decided it would be a great project and help make this my 'go to' BBC machine, along with the addition of a reliable storage using MMC.
The picture below shows the completed installation in a Master 128.
This remains a work in progress as I haven't yet got it to work.
