- Hello all, I have a pair of ethernet cards which I'm trying to
- find some information for. Distinguishing characteristics follow:
-
- AT bus, 16-bit full length card
- BNC connector only, no DIX connector.
- Intel P82586 Ethernet chip
- Hordes of 7400 series TTL level chips
- part no (I think) 204927-501
- other numbers on the board include:
- 204926-001
- 204926-901A
- 204926-902A
- 204926-904A1
- 204926-905A
- 204926-906A
- 204926-907A

- It may have been built by or for Compugraphics, a division of
- Agfa (at least nowadays), as it was part of a Compugraphics Integrator
- Series machine. I've tried to contact these people, but it doesn't seem
- that anybody much remembers these things :)
-
- Now, I couldn't swear to you it was ieee 802.3 Ethernet, but
- Between the intel 586 and the fact that it connects to a 50-ohm RG58
- bus type network, well, if it quacks like a duck . . .
-
- I've got all the i82586 based Crywnr packet drivers, but
- not knowing irq settings, or base memory, or i/o ports, these are
- like shooting in the dark.
-
- There are no jumpers on the board, but there are four banks of
- switches, arranged as such:
-
- -----------------------------------------
- | iP82586 |
- | |
- | SW1 SW2 |
- | |BNC
- | |
- | SW3 SW4 |
- | |
- ----------------------------------------
- ||||||| |||||||||
-
- Note: the switches aren't labeled, that's my doing.
-
- SW1 = 1111
- SW2 = 0100
- SW3 = 00010000
- SW4 = 0000
-
-
- So, any guesses, helpful hints?
