Spider-Man, The Amazing
Gottlieb, 1980I picked up a Gottlieb Spiderman a while back and finally getting around to working on it. It was missing its CPU board but I was able to pick one up. However, the CPU is missing the ROMs at PROM1 and PROM2. I downloaded the ROMs and am ready to burn but not quite sure what size chip to use.
I'm thinking two 2716s but want to have someone else confirm or deny. Thanks.

The original masked ROMs were 2708s.
If the board hasn't been updated, you'll need to do that.
Then burn a single 2716, with the ROM images combined.
