My company installed a several hundred IBM PC Network equipped workstations
"back in the day" ;)
It was a very stable network and had the advantage that one could use existing
75 ohm cable that could be simultaneously used for video (although, most of
our installations were network only).
IBM's NETBIOS was integrated into the IBM PC Network board. I wrote a
network utility program to analyze NETBIOS networks (which was advertised in
"Byte Magazine"). My largest software clients were TRW and the U.S. Navy. I
tried to get the U.S. Navy as a client (unsuccessfully) - as they had bought
my utility software and complained to me that it didn't support their 10,000+
Unfortunately, I long ago got rid of all my IBM PC Network cards and related
hardware. (I still have some IBM Token Ring stuff, though).
We also had several clients who "picked" Arcnet. We never recommended it - but
IT folks had their own opinions - and we were a network/system-integration firm
and would do whatever the the client asked for. (We later got to convert all
of our Arcnet clients to IBM Token Ring or Ethernet. Kinda like "double
By the late 1980's I had converted all of our clients to Token Ring
(especially those with IBM Mainframes) or Ethernet.
All the PC Network hardware was ultimately scrapped...
