Thank you very much!
Mine also had a fair amount of glue, but nothing a sharp blade cannot fix
WHOOPS ! (oh not not him again)
Re: WHOOPS ! (oh not not him again)
By the way, can you tell if the eprom type is 2732 or 2532?
My guess is that it's a 2732, but just to be sure.
I also prettyfied the IC list and added the needed datasheets.

It's a 2732, verified by checking that A11 from the cartridge connector is wired to pin 21 on the PROM.

Any chance of a picture of the underside of the PCB, Rolf?rolfmichelsen wrote: ↑Tue Mar 10, 2015 10:13 pm It's a 2732, verified by checking that A11 from the cartridge connector is wired to pin 21 on the PROM.

Excellent!
I'll do some work on them and upload them to their rightful place

Aaaaaand, done!

Can I bother you to take a picture of the component site with the socketed chips removed? That would make it easier to create a "X-Ray" composite image where all the tracks can be seen.

Another set of picture that will hopefully satisfy everybody's curiosity... It should be possible to see most of the capacitor ratings on these two pictures, but not for the smallest ones... The transistors are BC 549Cs.
