The connector is a super-high density 60 pin one,
identical to those
used as serial interfaces on Cisco 2500 series routers. 4 rows of 15 pins
each.
If anyone is really interested in trying to get Indy cams to work with
older systems, I can supply some of the funky Cisco 60-pin cables. These
are from some V.35 clone cables we had made up some time ago, but are now
obsolete.
