I'm almost certain that the video is standard,
plain
old NTSC RS-170, which you could probably hook up to
any modern TV having a video input with a simple
mechanical adapter. Much as it makes me ill to mention
this, but Radio SH**, which has gotten enormously
worse in just the last 3 months, probably will have an
adapter to a more modern RCA for it. You MIGHT be able
able to get a decent display from an RF modulator but
at 64 characters by 16, it would be close.
Nah - can't do that! I still have vivid memories of how my NASCOM-1 TV display
jiggled up and down back in '78! This time I'm splurging on an eBay composite
monitor, and Jim Battle kindly clued me in where to get an appropriate PL259 to
RCA adaptor for my SOL-20.
I'll admit though that I do use Radio Shack when gotta-have-it-now overcomes me.
