Hello everyone. I hope maybe someone has a little help for me. I need to
connect a old SS20 to a network with the old 10base 2 coaxial standard. I
know this is a little unusual but it is for a project I am doing. Does
anyone have a Sun part number for a network card that would allow me to do
this. With the 10base 2 standard so old I am having trouble even finding any
old parts. I know the old SS5's used this standard as the SS5 was used as a
workstation for the old Cray's. On the Cray 916's they used the SS5 as the
workstation networked with the old coaxial cable. Any info would help, Thank
you

Your best bet might be to find a hub that has both RJ-45 and coax
connections.

Try searching for a 501-1881

Look on the back. You will see two connectors which look like
shorter versions of the SCSI connector, one above the other.

One is marked: "//"

And the other: "<...>"

The one which is marked "<...>" is an ethernet connection, which
simply requires an adaptor to the standard AUI connector (D series
15-pin connector). You plug the adaptor into the computer's jack, and a
10Base2 transceiver into the other end of the adaptor.

Most that I have seen are only a few inches of cable between the
connectors, but the one which I happen to have ready to hand is closer
to about four feet. It has the Sun logo molded into the AUI connector
end, and both the Sun logo and the ethernet symbol "<...>" moulded into
the other end, but has no moulded part number.

However, on a very faint label a couple of inches from one
connector is the part number:

530-2021-01

with the "-01" probably defines the length of cable.

Of course, this presumes that you can find one of the
transceivers, since those have been mostly replaced by 10BaseT ones, and
those with built-in ethernet in the 100BaseT speed range by now.

A quick eBay search discovers an M-II to AUI adaptor (four of
them in one auction, actually), but noe of the unnamed earlier
connector. A quick check shows that the connectors have different
numbers of pins, so these won't do for you -- unless you also get an
hme0 ethernet card with the M-II connector.

The auction number is: 5785719456

I'll leave it to you to find hme0 cards. :-)

I've also got examples of hubs with mostly 10BaseT sockets, but
one 10Base2 and one AUI, and even an antique box by DEC with one 10Base2
and one AUI. Far too big for what it does, but those are some of the
options.

Good Luck,
DoN.

Thanks for all the help guys, looks like I am going to be using a few
different things together to get it to work. You would think old Sbus cards
would be cheaper than they are. Oh well. I want to thank you all anyways,
have a good holiday. Bob

I just got around to checking my stash of S-Bus cards and find I have
two (2) network cards.
They are 501 2015 and have both a SCSI and 10base2 (looks like
telephone jack)

How about $10.00 plus shipping for one of them.

10base-2 uses a BNC connector (or an AUI and a dongle), not a
telephone-jack-like connector.
