Looking for an 82S83 (or 74F583) BCD Adder IC for my 6790 - or sources 
for same.

A suggestion for 6790 owners:  consider replacing the 12,500 UF filter 
cap on the 5 volt supply as preventive maintenance; it seems to raise 
havoc when it fails.

Also - wonder if anyone knows what became of the big pile of non-working 
6790s that were sold at Dayton last year?  All went to one buyer from 
what I was told, so there ought to be lots of parts out there somewhere.

Thanks and 73,
Bob W9RAN.
