Does anyone know what chip was used for the MITS
serial boards? I thought
that it was the 6850, but I could be wrong.
Weren't a lot of people using the 8251 back in those days?
I had to play some tricks in getting an interrupt-driver
written for the 8251... this was for the redoubtable
Data General One, a sort cool, sorta nasty laptop...
