Hi all,
as part of an arcade PCB repair (vintage cpu board, so kind on topic!), I need a new MB7052 256x4 TTL PROM. I can't program TTL proms with my current programmers (and I've been trying to find a suitable old Data I/O for years in EU, with no luck). I'm looking for someone that can program this for me, and of course I will refund all expenses. However, the person would be best located in EU or Italy, to save on shipping costs (however, I'll consider getting the part from another continent if nobody else can do this job in my continent).
I'm quite sure the PROM can be a compatible part and doesn't need to be the Fujitsu one, but arcade designs can be very tricky (and this one is definitely tricky).
