I have an Apple //gs system at work along with my personal Amiga 1000 and 1080 monitor. The //gs has the Apple RGB (pretty, with total glare) monitor, which I wanted to see on the 1000. So I built a cable to tack on to the 1000 to 1080 cable for the Apple, and voila, the Apple RGB screen worked just fine on my Amiga. (For the curious, I didn't build a 1000 to Apple RGB cable because I didn't want to find a DB-23, didn't want to hack a DB-25, and had DB-9s sitting around.) Eventually, I built a cable to go from the //gs to the 1080. (Didn't have a DB-9 gender changer to use with my existing cable.) I plugged it in and nothing happened. I triple checked the cable and it seemed fine. I finally took a voltmeter to the RGB ports of the //gs and 1000. It turns out that the 1000 was putting out 4.68 volts and the //gs only 3.9 on composite sync. Just for fun, I then put a battery between the //gs and the 1080 on the sync signal, and I got an slightly unstable picture. (Not that it lasted long.) Any ideas about how to get an Apple //gs and Amiga 1080 talking RGB to each other? (Please, no flames about why I would like to do this. I'm just a twisted sorta guy. :-) Note that the 1080 still has to be perfectly usable with the 1000 RGB. -- Roger M. Shimada {amdahl|hpda}!bungia!gorf!rms rms@gorf.mn.org
