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...

I always thought the 8251 was a pretty kick-ass chip. I learned a lot
about it since the Royal Alphatronic PC that I've got (somewhere in this
disaster of mine) uses it. I was pleasantly surprised a number of years
ago when I discovered someone had made a BYE insert for it. :)
