For my Commodore PET main board Tester, I'm looking at hooking up the 8032 PET video (80 column X 25 lines) to an external monitor. I tried composite video to an old Sony Watchman TV, but the Sony could not sync the the PET. I think the older 40 column PETS are closer to the TV bandwidth, but the the 8032 has a higher Horizontal rate. I was wondering if anyone has had success using an old PC Monochrome monitor. The PET has TTL level Horizontal, Vertical and video signals. The frequencies are 20 KHz and 60 Hz vs the MDA spec of 23 KHz and 50 Hz. Is this close enough?
