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 :-)
