15 pin connector combined with BNC connector suggests it might be an Ethernet
card -- original 10 Mb/s. The 15 pin connector would be the AUI (transceiver)
connector. If the connector has a slide latch (to engage turret posts that
take the place of the more common locking screws) that would be a pretty solid
sign it's Ethernet. If so, the BNC connector should be insulated ground
(plastic sleeve around the connector body so it doesn't contact the computer's
chassis).
The easiest way to connect such a device to current equipment is to find a
10BaseT transceiver. Any 10/100 switch should talk to that, and compliant
Gigabit Ethernet devices will too (since the standard calls for them to go all
the way back to 10 Mb/s) though I would be less confident of that in the real
world.
