The other day, fixing my friend's ROM 3 motherboard with wierd
problems (certain programs worked on one but not the other ROM 3 machine),
I discovered that both of his ROM 3 machines have different ROMs !
Looking at a closer look, and comparing with my ROM 3 machine
back home, I found out that the ROM 3 machine in question, had a 32 pin
ROM FF-FE (located on UJ9, next to the 65816), part 341-0749 and sitted
next to it, is also a different ROM FC-FD, a 28 pin ROM, part 341-0728.
Both my friend's 'working ROM 3' and my machine had 341-0748
for ROM FF-FE and 341-0737 for ROM FC-FD, both 28 pin ROMs.
Anyone have a different part number ?
