View Full Version : Apple III+ and Monitor 100

November 1st, 2008, 06:00 PM
I just picked up a Apple III plus with a rgb monitor I think is called the Monitor 100 and seems to be so rare it almost doesn't exist. One thing I found said it had motorized screen tilt. This one is stuck in the all the way tilted back position and its a little annoying. I don't want to force it back too hard but, I've given it enough push that its obviously not moving easily. There are no buttons or anything on the thing besides a single power button. Anyone know anything about these things ? Is the tilt software driven ?

Also, there is a switch on the left side of the Apple III+ close to where you unscrew the top shell. I'm not sure what it does. Nothing seems to happen when I use it. The regular Apple III I have doesn't have it but, there is a hole in the frame when one could mount. Any ideas what this might be ? Nothing about it in the III users guide. Looks official though and not like some hack. Even has a proper label. Next step is ripping everything apart to follow where the wires end up and I'd rather not.

Open it up and see where the switch goes.

Haha that's the next step. I'm lazy though and there are a lot of screws between me and that motherboard. Someone out there should know what that does. The label make no sense to me though. A solid square vs a not so solid square. Boggles the mind.

edit: OK I couldn't stand it and looked. Just goes to a jumper next to the clock battery jumper that looks to be labeled J19 INTSW

edit2: It turns out to be a interlace/deinterlace switch. It makes the screen characters smoother. Seems to add a bit of flicker too which makes it more annoying then just the normal fonts to me.
