...a silly question occurred to me. Why bother with remodulating?
Why not just drive an RGB monitor with the demodulated output? I use
such an arrangement to view PAL-recoded VHS tapes and resulting color
is much better than local NTSC broadcast quality.

There's no reason why you shouldn't put it onto a VGA monitor, except for
aesthetics - a vintage home computer looks better on a vintage TV set, much
like I try to use period programs when demonstrating the TV sets (I hide the
PC under the table). When experimenting, I use a variety of display
devices - the console drives a modern 1024x768 TFT monitor, and for the most
part, the TV ouput drives a 1970 Sony TV9-90UB monochrome TV, which is dual
standard, and will display either 405 or 625 line pictures. I have a Melford
monitor which will handle 525 and 625, and use a Tektronix 535A scope (circa
1960), with a type O plug-in for esoteric standards, but when it comes to a
demonstration, a 1950's TV set displaying a 1950's program is very
impressive. The advantage of the PC method of picture generation is that it
gives the maximum possible resolution on a set (assuming a well desinged
modulator).
