You certainly could put a correct pin out EPROM in one of the sockets
and read it / write its contents to a disk.
Nanoman.

Chris, the ones I think were in the clones were 2764's. I only went
from IBM PC to clone and the proms they had though compatible with the
eproms didn't work in clone boards, so you needed a prom / eprom part
reader to get the data and then write the eprom.
Looks like 64k X 8, which are 2764's

The PC / AT had different proms and they were 8 bit parts but on a 16
bit bus, so the bytes were interleaved.
I didn't find a tech reference for it in a short search.
