I don't know whether they contains BBC ROM stuff or not. If anyone
would like to get them just pay shipping and I'll send the EPROMs.

Under the bolts there is a handwritten label that says. "Test OE2F

After reading your responses I'm thinking of keeping the TTL-logic
chips, the 6502, the Z80 and parting with the rest of the chips.
Anyone interested? ;)
Cheers,
