Ahh yes I remember that...I had an XT clone for a

V20; quite the screamer at the time!) and I managed to find copies of
the IBM BIOS w/BASIC, and ran those in the board...worked nicely. As
I recall, the BIOS was one EPROM and the BASIC interpreter was the
other four, and they were optional.
ahh, but do you know WHY the 5150 had those 5 ROMs, but 6 ROM sockets?
I recall something about BASIC.COM (or was it
BASICA.COM?) being
basically a wrapper around the stuff in the ROMs...Did it add any
routines like disk I/O or anything like that?
YES.
It even replaced a few routines that didn't work right
