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
http://www.highway.net.au/parts/converters/1488.html)
THe 'few resisotrs' will turn a CGA digital signal into an analogue RGB
signal at the same scan rates. For example, you could feed it into the
RGB intputs on a TV SCART socket.
What the 'few resistors' don't do is convert the 15.7kHz CGA signal into
a 31.2kHz VGA signal. If your display can handle the lower scan rates,
then fine. If not, it's not going to work.
