Got the unit on the bench over the weekend, and everything seems to work just fine. All the patterns display properly, RF frequencies all nice and stable on a counter, and all the drive signals look good on a scope. Replaced the line cord, and swapped the 3 front panel RCA jacks (30 Hz Servo drive, Video out, and 3.58 MHz drive) for BNCs. Why would they even use RCA phono jacks on this kind of equipment? BNCs are much more rugged with stuff being plugged/unplugged all the time.
How many different accessory units were made for this thing? I know of the NTSC pattern generator and the VCR test unit. Any others?
