Hello,

I am trying to connect an Apple IIe RGB card (from Apple) to an AppleColor RGB monitor (the one of the IIgs) but it doesn't function. I suppose that this card gives out digital TTL RGB levels that the monitor probably won't accpet, am I right ?

I have the manual of the card but it doesn't give any technical specs, so I can't say if it's digital or not ... I also have another RGB card (not from Apple) which is working correctly with that monitor, but that has s a completely different layout, hence I suppose it's giving analog output.

I've read on a technote that :
"generating an analog signal is possible with a resistor network (an example of
this is given in the Apple III Owner's Guide)"

if my suggestion is correct can anyone publish this schematic ?

Thanks

Your are most likely correct. Most IIe RGB cards are digital RGB IE they will work with OLD CGA/EGA monitors.
