Did he ever have an Apple II or something of similar era? My wild stab
in the dark is it's a serial interface card for an Apple II or
similar. Whatever it was didn't have a convention of using PC-Style
backplane brackets but instead had a ribbon cable hung out the back,
which I believe was how some A II were.

It look a bit like an ISA card missing it's bracket but I've not got
one to hand to compare it too. Label shows a horse, CP Computer
Products, Power Products Division and a matrix printed "PM671R".
Underside has "Artwork PC19640, REV.B. Detail PC19641. Assembly
PC19642. G T P 244" in copper.
Main chip is an AMD Z8530PC. There's a PAL and a MC1488 & 9,
otherwise the rest is 74LS TTL. All socketed. 26 pin internal header.
No external sockets. Date codes are mostly 1987.
It certainly feels like some sort of RS232 serial card, based on the
chips, but I've not seen one without an D-type socket on before.
Any ideas? Anybody have a use for it? FTGH just pay postage.
