Al,
Would you be interested in Bridge Communications:

Ethernet System Product Line
Software Technical Reference Manual
Volumes 1, 2, 3

Dated July 1983

John.

the PC network tech ref has been up since Feb 
(6322916_PC_Network_Technical_Reference_Sep84.pdf)
which has the tech details

I finally found one of the 5178 frequency translator boxes on eBay a few months 
ago which you have
to have to flip the transmit and receive frequencies, and I have some of the 
Sytek serial-broadband
boxes as well though they may run on different tx/rx pairs.

Cool!  I worked on that (at IBM).  ;-)

Re: Bridge Communication Unibus Ethernet board?

[Al Kossow via cctalk]

Also, I'm interested in archiving any surviving documentation for the first 
generation Ethernet
stuff that I don't have up on bitsavers like Bridge and Ungerman-Bass. I have 
some Interlan and Excelan
manuals, but I've not turned up much from others. I have stayed away from 
Cisco, though.

One of my background projects has been trying to collect enough parts to bring 
up a Sytek broadband
network, which IBM also sold as their first PC LAN.

try dumping the eproms and see what the strings say

it looks like a Bridge PCB layout

their products were all 68K based

It says IECU. I wonder if that is some kind of product name? The copyright
in the etch is 1984 but the chips are mostly from 1985 or 1986.


Hmm, we have several Bridge CS/1 terminal servers. Maybe your board is an 
integraded terminal server to telnet into virtual serial ports or to 
connect to telnet ports via emulated serial lines. I'm thinking of 
something like a DZ11 on the host side and ethernet/telnet on the other 
side, all on one board. IECU may stand for "integrated ethernet 
communications unit".

Check out

 which has a lot of clues.

Unfortunately Volume II doesn't seem to be online, and would be even more 
helpful based on its TOC.

No M marking on the handle.

Plenty of onboard memory just for packet buffering?

/Mattis


Never seen before.
Is there an “M” nummber on the board or on a handle?

As the DELUA uses the M68000 and this board apparently too,
but with *two* headers (DELUA has one), a network bridge is
plausible. Is “Bridge Communication Unibus Ethernet” in the etch?
