The Rainbow does operate at standard TV rates, i beleive. The monochrome
signal is actually a straight composite signal, meaning, if you build an
adapter, you can connect any old composite monitor to it. I used a
Commodore 1084 (I think that's the model...) for a while.
Indeed yes. And the VR201 can be used as a composite monochrome monitor
with other TV-rate machines.
Note, however, that 'composite video' does not imply TV rates. I am sure
I've seen an HP composite monitoe that was soemthing like 22kHz horizontal.
One of the oddest features was that you could switch to European rates at
any time through the bios. Just press F3 while the system was on to get
to the Set-Up screen. One of the flags was 'Frequency' and it presented
two options: 50Hz and 60Hz. Just flip the flag depending on your
continent, and you're all done.
Ah, right. I knew the VT100 had that feature (and the Rainbow's text
video system on the mainboard uses the same custom chips as a VT100),
but I couldn't rememebr if they'd left the setup option in the 'bow
