I used to combine h and v syncs to green with only a
resistor (somewhat but not entirely related I guess).
Don't ask me what the value was though. As I recall it
wasn't terribly crucial though.

What was the
pinout/schematics of such a cable?
How did you handle the
intensity bit?
From memory, and it was a while ago, we had three
voltage dividers to
knock the TTL outputs down to .7v, and then three
more resistors from
the intensity bit to the analogue outputs.
There may have been some diodes there.
The sync combiner was a couple of resistors and a
transistor.
