All 3270 stuff uses BNC connectors. I don't know offhand which
impedance of BNCs they use (they look like 50-ohm to me) but at those
frequencies, a few MHz, the impedance bump really is minimal.

NO NO NO NO
NO! RG58 is 50ohm, 3270 is 93 Ohm so RG63....
What's the BNC for, then? As far as I knew, they only made
50 and 75-ohm BNC jacks. Or did they just use 75 ohm ones
and hope the brief blip on the TDR didn't do too much to
the signal?
