The cables I have (not made by DEC) are realy, clearly marked with
"50 OHM CHEAPERNET 10BASE2". I got them with a QBus to CI and CI to SCSI
setup. I handed the CI stuff, with the exception of the cables, to a
friend some years ago. So I can't be more speciffic. I suspect CI cables are just ordinary 50 Ohm coax, but
heavily
overspeced in best DEC tradition. ;-)
I agree (now) that they're most likely 50-ohm, but that particular
coax is anything but ordinary. ;) I'm sure they over-specced it like crazy.
