thanks to all for the info.
i think 25 bucks for a standard RJ45 is looking awfully appealing right
about now.
so that leaves one more of these cards if anyone wants it for the price
of shipping. $5.00 US Priority Mail. the other one is spoken for.

It probably is an Ethernet MII interface
connector, which was used
on many SBus cards, for space reasons alone. The MII (Media Independent
Interface) was a "generic ethernet" connector that could be used for
10, 100 and even 1000Mbps media, using a transceiver of some kind to
connect the controller (chipset) to the media (cable), much akin to
the old (10Mbps) AUI interface.
Both of my SBus cards (one with dual Ethernet, the other Ether/SCSI)
have MII connectors. You need an MII->UTP, MII->BNC or MII->AUI
transceiver to hook it up, obviously. :)
Actually, no, it's not an MII interface. Those (at least the pair of Sun
ones I have) are wider connectors, similar to a high-density SCSI
connector. That connector is a mini AUI connector (or with the proper
cabel and setting on the board, it becomes a 10BaseT port. I don't have
one of those cables, however.) I don't think you could fit a SCSI
connector and an MII connector on the bracket of an SBUS card, anyhow.
IIRC, MII has about 34 pins. If I felt less lazy, I'd go look at the one
on my Ultra 1...
Fred, do you know what number (Xnnnn or 501-mmmm part number) those cards
with the MII connectors are? I'd like to see a picture of how they fit
the SCSI and MII connector on one card.
