A motherboard (which is unlikely), the board you already have will do DHR. No modification is necessary. If you're using an Apple extended 80-column card (or maybe some clones), there's a jumper on the card that should be installed to enable DHR.
HiI'm wondering what that jumper would be doing. Just connecting two signals from the motherboard?
I have two 80column/64K cards, both "clones" and none of them have a jumper.Also none of them have RGB output so I'm wondering if it would be easy to make this circuit myself, to produce the RGB signals. I have been searching the net for info on that but haven't found anything specific.
My IIe is also rev. B and unenhanced.I'm rather new with Apple II. It was a friend who had one and I recently bought this IIe. My old machine from back then is a Video Genie, a TRS-80 Model I clone. (Apple II was too expensive.)
