The PROMs are most likely house-labeled Intel commodity parts with
JEDEC-standard pinouts, so it should be fairly easy, using an EPROM
reader, to figure out if these are 8KB, 16KB, 32KB or 64KB devices.

I suppose one could find representative known Intel samples and compare
the appearance "under the window", but I've never done that.
