I have 3 Tempest PCBs I'm trying to work with, and I've noticed on 2 of them that the ROMS read "115", "116", "217", "118"....... and so on.

Is this normal?
 
Yes,

The 217 is the fix for the backdoor and score problems. You might also see a 222 which updates the self test with a line for the spinner check.

The other option is version 3 done on 2732 roms, where everyother rom is missing. But that requires the correct version board, and jumper placements.

thanks and be sure to see my update in the other thread!
