Inside each box in a static bag are ISA serial boards,

enough to know what if anything is special about them. UM82C11 in a

I don't know about this card. I would be interested if it does turn
out to be encryption / cryptography related. I would of expected a
very limited number of companies selling encryption devices in that
era. IBM, NCR, and other "bank friendly" companies.
Second board has Kouwell KW-524H printed on it, its
smaller with a
Winbond W86C452P 248NI425630 as the only big chip.
Possible not. It might of simply been an ISA serial port card
connected to an encryption device, or encrypted line (say a router
and/or modem with X.25 to a bank for example).
