Need instructions for Enhanced Cable Tech "Liberty" VGA adapter....
I'm trying to get my old PowerMac 8500 up and running. The only display I have that is (well, should be...) compatible is an old Apple Studio Display 15" Flat Panel (Rev B.). This is the second iteration of that display, with the VGA connection, not the earlier Mac 15 pin D-sub connection, which is what the 8500 has ( http://support.apple.com/kb/SP135).
I have two adapters that I'd think should do the trick of getting me something on the display. An NEC MultiScan unit that has several resolutions printed on it, but no adjustments, and an Enhance Cable Technologies Liberty adapter.
The NEC one gets me noplace, and so far, neither does the Liberty.
The Liberty has a knob with several letter stops (A-M or N), and a set of 9 (I think) DIP switches. Instructions on the back list many resolutions, but only give instructions for the last 3 DIP switches, which are for sync. It mentions to consult the instructions (which I can't find or don't have) for using the other DIP switches to get "expanded" ID codes.
I've tried all of the knob stops, and a couple DIP switch settings, but nothing seems to get me an image on the display. The display does work, it just isn't detecting a signal, and it will tell me so.
I think the 8500 may be going into "headless" server mode (no video) when it can't detect a monitor attached, so once it boots (and it IS booting), I can't get anything until I re-boot again. I'll have to dig up an OS9 install CD, to see if that helps me any. When I stored it some years ago, it was running Mac OS X 10.2 via a boot loader (it has a Sonnet PPC G3 processor upgrade card), so that may be an issue, too.
But, I was hoping that maybe someone has the instructions for the Liberty adapter kicking around in their junk drawer. All I need is the instructions for the DIP switch settings.
