If this means each board having all three connectors (BNC, RJ45,
AUI), there is a company that makes boards for GVC technologies in Sparta,
New Jersey. The model is NIC-2000BT/1 KC3303-05. This is an NE-2000
compatible board with the usual 300/310/320/330 hex and IRQ's
3,4,5,9,10,11,12,15 using jumpers. These I suspect to be old boards (mid
1993), so getting them used will be a matter of attending a used-parts
computer show. :)
