No one ever called it a "Digital Ethernet Personal Computer Bus
Adapter", just a DEPCA. I never previously knew that there was any
meaning behind the DEPCA name.
Yes, that's what it meant. "DELNI" - Digital Ethernet Local Network
Interface. "DESTA" - Digital Ethernet Station Termination Adapter.
DELQA - Digital Ethernet Local Q-Bus Adapter (this one probably means
something else. Working?). DEMPR - Multi Port Repeater. DEREP -
Repeater. And so forth. Yeah, nobody spelled it out, but those DExxx
names usually meant what the device was. DEBNT, DEUNA, DEQNA. Same
naming convention. I'm probably missing several.

The DEPCA manual
(http://www.bitsavers.org/pdf/dec/ethernet/depca/EK-DEPCA-PR-001_Apr89.pdf)
says "DIGITAL Ethernet Personal Computer Adapter", without "Bus".
DELQA was "DIGITAL Ethernet Local-Area-Network to Q-bus Adapter"
according to its user guide.
It's predecessor, the DEQNA, was "Digital ETHERNET Q-Bus Network
Adapter", according to its user guide, or "broken", according to most
people :-)
