I already performed the surgery succesfully. I did use the provided
EPROM and caps. I also tried the old EPROM after the operation. It
worked. Nevertheless the program inside it was different from the new
one, so I did put the new EPROM in.
If I remember correctly there was an A1 mark on the new processor,
while on the old one there wasn't, so you're correct.

Thanks Per-OlofI already ordered and received the kit TZS9EK0021 you mentioned. It
contains all the items you said. The chip on the PCB however, is the
VDP3108A, so I suppose its the new one. The chip in the kit also says
VDP3108A. I suppose I can use this chip to replace, and not use the
provided EPROM. Or should I still order another replacement?
As the price is about the same here in sweden for the kit VS the
"VDP3108A PPA1" i allways order the kit.
If i remember correctly the VDP3108A on that kit is the "A1" version
of the VDP , are you sure it isnt printed "A1" on the ic on that kit?
If it is, and the faulty VDP hasnt that mark "PP A1" or "A1" then you
need to change the eprom and add the capacitors!
