 It looks like a ROM card. I'd check the pinouts before
plugging it into a PC. Many cards like these were for
various proprietary busses and have the power leads in
different locations.
 If it is for a PC, trace down the address leads from the
edge connector. These will usually go to some kind of
comparitor ( ls688 or similar ). You should be able to
figure where to look for it in the address of the PC.
You can then use some simple code to transfer the EPROM
to a disk file.
 Still, doesn't look like a PC card so be careful about
plugging it in until you've traced a few leads.
