would have thought these were more relevant to preserving or documenting the
IBM Cabling System. I wonder if any one is interesting in preserving or
re-creating this type of network. Does Al at CHM, the folks at MARCH or
TNMOC have any plans to demonstrate this sort of early structured cabling
systems,,,,
Ugh, I used to deal with these by the hundreds at $work ca. 1997 or
so. The building was wired with IBM Type-1 (at least what I
understand to be called Type-1, and what is in Cindy's pic) connectors
in floor cells in every office cubicle. PCs had IBM or Intel ISA TR
cards which were connected with 9-pin to Type-1 cables into the floor
cells. As the building networks converted over to Ethernet, we used
these BalUns to run Ethernet through the Type-1 jacks. Probably not
"up to code" and probably not the optimal media for Ethernet. These
were the 10mbps days, too, so in the few cases were we had 16mpbs TR
to the desktops, (theoretical) performance actually decreased!
Anyway, I have a couple IBM MAUs with these connectors, so I'd be in
for a few BalUns. I will email Cindy directly.
