It seems to my memory that we used just a RCA phono jack to the board, and RG58 with RCA phono plug on one end and a BNC on the other with a standard black and white security video monitor in the field, typically already located at the site as part of the existing video surveillance, so service personnel didn?t have to carry anything with them. We used a RF modulator, channel 3 or 4, on a larger screen TV set in engineering spaces for ease of viewing when developing or modifying the embedded application we were running on these, again it seems to me we picked that up at Radio Shack when we needed one back then, and fed it directly from the OSI board. It seems to me we got power for the modulator from the same connector that the video appeared on. We ran these on a battery backed up linear power supply, in the event that AC was lost to the facility. We didn?t need video with our application, so video was never left running in the field. I can?t remember when I last had that Superboard fired up, but I did it with a 5? black and white security monitor from my truck I use to setup video camera views with. Nothing extra involved, and it hasn?t been powered since. It is stored downstairs with the PET and a Data General Micro Nova.
