There are a few similar machines which are covered by MAME - that's a free program you can run on the PC, which emulates thousands of arcades and coin-ops. You just need to get the ROMs from somewhere, figure out how to use MAME, and choose the right model of machine. I can't help with that, but there will be plenty of MAME support forums.
http://mamedev.org/release.html(If you don't care too much precisely what game you run then MAME is certainly the answer.)
The more chip numbers you can see, the better - is there sound in this game? Can you find the number or name of the sound chip?
Can you clean the crystal (the metal can, top right) and read off the frequency? Could be 16MHz, could be something else.
Two machines which might be similar, but might not be identical:
Fun World / TAB / Impera
Series 7000 hardware.
65C02 + 2x PIAs + M6845 CRTC + AY8910
and
American Poker II (see
here)
Do be careful visiting web sites about poker machines and ROMs for them - there will be scams and there could be malicious popups and similar.
(About the 32k ROM dump: it's actually just 8k of ROM and about 64 extra bytes of code which is probably some kind of copy protection, perhaps in some kind of mini-ROM.
