Hi, I'm considering to buy an RGB/80-columns card for my IIe. Will a card from USA would work for me in my European Apple IIe?I think of the frequencies... My IIe is for 50Hz power and outputs a 50Hz signal for video. Americans use 60Hz for power and video. So would an RGB card from US output 60Hz video in my machine which would be incompatible with a European monitor?If this is a problem, would it be possible to modify the card to 50Hz (by changing a crystal or something like that)?Knut
When you say "European monitor", which monitor are you intending to use?Do you have an AppleColor 100 RGB monitor (model A9M0308)? As far as I know, this is the only monitor that will work with the Apple //e Extended 80-column text/AppleColor adaptor card. This monitor uses digital TTL RGB signals - you won't get good results if you try to use an analog RGB monitor like the one sold for the IIGS.
Unfortunately I don't have the manual for this monitor, but the label on the back says "Model A9M0308, 115 VAC, 60Hz, 1 Amps"
