unlabelled bare Eurocard-size PCB, figured out that it was for an Acorn
'System', then worked out what the chips had to be and then worked out
what the passives were as well. For the record the main chip was an
AY-3-8910 sound generator interfaced to the 6502 bus by a 6821. Other
chips were TTL for the address decoder, space for an EPROM, and a small
audio amplifier.
Tony, you're a wonderfully sick man.
