Hi All, I wanted to share the results of my simple experimental modification for the AppleColor RGB Card, it allows to use an Analog IIGS monitor with an AppleColor TTL RGB Card, hope you'll like it. http://www.exosystem.it/apple2/TheMarcorlandiModification_TTLRGB.pdf Quite often some of these cards appear on ebay,but not everyone knows that it works just with old TTL/CGA or the Applecolor100 monitors, here's how to modify it to make it work with Analog Monitors.. Suggestions are welcome Have Fun :-) Marcorlandi 'mirko'
