Hi smf,

I think it said 34518 was available.  I have it taken apart right now so that I can re-cap it.  The 22uf capacitor was waaaaay off and the two big 1000uf capacitors are not looking to good either.  The Z-80 Video Pak gets really hot (voltage regulators) when in operation.

I uploaded the manual in PDF for mat for you.  It's very short and has no information on how to use the Z-80 CPU.

Just curios.... what are you building? :)
