I just read some post on the 'net regarding an adapter as possible:
"Converting CGA digital RGBI signals to VGA analogue signal just takes
few resitors. That matches the RGB signals from digital to analogue.
Been there, done that."
This smells funny. Is that all it would take? A double-scan converter
is typically $100 and has many more components (for example

I had an old Multi-Sync 2 monitor which had a
9-pin (DE9) for TTL and a 9-15
pin adapter dongle. I remember using it on an old IBM and a Compaq with a
VGA card. I know I don't have the monitor but I'll have to look in my
"stock" for the adapter and see what's in it.
You are right, though. The T2K sync frequencies are very low...26.4k I
think, but I'd have to check my notes.
There were several of these types of monitors. Mitsubishi had a few
DiamondScan models that had RGB BNC connectors, as well as TTL and
analogue connections--and there were a few switches on the rear of
the unit to select what was what, along with different adapter
cables.
I still have one that I use with a PAL VHS VCR and a decoder to watch
my old tapes of the Edinburgh Tattoo...
