IBM 5161

the "blue" card sounds more like an arcnet card rather than ethernet.
Ethernet would have a BNC and a AUI 15 pin DB type connector
on the back. The arcnet card was a coaxial cable type connection.
The blue really rings a bell asn well as the processor. I did
a bit of work in the early day with arcnet before ethernet became
the standard.

best regards, Steve Thatcher
