Anyway, the output of the convertor would be 625 baseband video, so almost any moderately recent TV should be OK. But, as I said, check first.
I'll probably do this as a SSTV/NBTV to 625 convertor as a single unit to drive a separate TV/monitor. I think this would be more useful to others if they wish to copy and/or modify it. A SSTV/NBTV to 800x600 VGA version may follow on later.
