Apparently there actually is an equivalent EPROM,
according to this
datasheet for the MM4203/MM5203 EPROM:
http://www.datasheetarchive.com/dl/Scans-006/Scans-00137265.pdf
It states they are pin-compatible to the MM5213/MM5231 mask ROMs.
Interesting. I checked the MM5204, but not the MM5203. The MM5203
requires wiring for pins 22 and 23 that the MM5231 doesn't, but other
than that it does appear the same.
