AY-3-8910 Adapter PCB
This is a blank PCB which when assembled allows you to convert the AY-3-8912 sound chip, which is much harder to find and getting expensive, to the AY-3-8910 which is used in the Oric-1 / Atmos computer.
The assembled PCB is for reference only. You will need to source and solder in the components yourself so will need to be reasonably good at soldering.
I’ve built this PCB and it works perfectly, along with the main board and keyboard PCB’s which I also sell in separate listings.
