IBM PC Network

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+ workstations! 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 dipping" ;) 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... Cheers, Lyle -- -- 73 NM6Y Bickley Consulting West https://bickleywest.com "Black holes are where God is dividing by zero"
