IBM broadband adapter card

[Karen Linde]

This is a shot in the dark.

I need an IBM broadband adapter card, RG-11 with a UHF connector.

I called IBM and they said, huh? I guess it's old technology, one source said
I may be able to get one used. Does anyone know what I'm talking about? Any
clues would be appreciated.

THanks,

Egads, I thought these died a peaceful death years ago. I believe you
are referring to the "IBM PC LAN Adapter", widely used prior to the
introduction of Token Ring aroung 1984-5. The system uses a CSMA/CA-like
protocol, and operates at 2 Mb/s over a Broadband (private Cable TV)
network. It was built for IBM by a company called Sytek, which was later
purchased by Hughes Corp. and changed its name to Hughes LAN Systems.

A major part of the reason for the demise/acquisition of Sytek was the
precipitous drop in sales of the Broadband adapters after the IBM switch
to Token Ring.

I doubt if they still offer the cards for sale, but you might try them.
They are in Mountain View CA.
