large piggyback "M-28-S2" and a sticker with "TAB AUSTRIA 7-85"

20120107 update from Kirmo: "I had an opportunity to dump the Pitfall II (bootleg) PROM (TBP24S10 at location 10M IC76), and it's identical to the one already emulated in MAME (Pitfall 2 315-5093)"

This is not an original Sega PCB, it's a bootleg using same ROMs.
