David: I have two 20" SuperMac monitors here I bought at auction that use those three RGB connectors to plug into the monitor. But that's it. The opposite end of the cable fits the Mac's monitor port or the connector for the SuperMac video card.
Last summer, I had a high-priced "surge suppressor" that failed during a thunderstorm. That monitor got cooked. It's in a closet to this day. For some reason I can't bring myself to dispose of it. My other one is sitting on the floor by my feet. And has been for six months. It has a mysterious short in its power switch. This puppy will sit there for another 12 months before I work up the courage to crack its case open and replace the faulty power switch. I know how to discharge a throwback transformer. But it's such a distrubing experience, I'd rather wait until the capacitors, etc., have a chance to "cool down" voltage-wise. It's a difficult wait; almost like waiting for radioactive waste to reach its half-life!!! Hearing that loud *POP* is almost as loud as a .38 Spl. snubnose revolver going off at close quarters. I know because I've done it before. I had a double-page display monitor at one time (B/W only as it turned out -- NOT grayscale) that had only a "coax" input into it. I gave $3 for it at auction, but ended up paying a landfill fee for it. It required a proprietary video card, which the idiots I bought the thing from didn't know about or mention. What I NEED is Pickle's "Knowledge Database" before I ever go to another auction! That, or hunt him down and drag him along with me! ;-) Allen ----- David Pierce wrote: > > It occurs to me that if none of us can remember this thing, it has to be > realy old.
