Very enlightening.
You're hoarding interface ICs with commercial second thoughts while 
deeming any usable alternative as not working crap. Sounds quite coherent!

BTW Why isn't there a separate list "ccbusinterfacechip" where those 
recurring 8881 discussions can be separated from the more interesting stuff?

I just can't imagine that it should be a real problem to build working 
Unibus equipment without the old chips.

The Unibus design is from 1 9 7 0 (or around that). Just read that 
sentence loud.

Kind regards
