You know those things really are all over the place if you stop to
look.
I have '90s vintage Personal Iris (in another lab, still working) w/
an
AUI (it goes through an AUI to UTP transceiver). Also that single
board computer in the mass spec I come to find out uses an AUI
(it too gets turned into UTP). Until a few years ago we had a DEC
DELNI that was gathering dust.
