As I remember the correct cable also includes an 8 pin
keyboard connector.
Does anyone else remember?
I remember it doesn't. The colour monitor cable, for the VR241, has a 4
pin keyboard connector in the junction box , and 3 pigtails ending in
BNCs for the monitor. But the VR201 (mono) monitor has the keyboard
connector (4 pin, of course) on the back of the monitor, the CPU-monitor
cable just has a DA15 at each end.
