I believe what Bob Ames thought was a PROM is really the replacement
8530 Serial Communications Controller chip.  I don't know the whole
story, but apparantly some of the 8530s that were used in some combo
boards had some inherent defects which caused a port to lock or
computer to crash when a lot of I/O was happening on the combo ports.

I have the new 8530, and my board works fine with a VT100 connected to
it at 9600 baud.
