New apple IIE now what?

Submitted by unitednations161 on October 6, 2016 - 7:56pm

Just picked up a IIe, well two IIes and 5 disc drives a monitor and a 512k. I remember these in elementary school, but I'm unsure what to do with them now.

The easiest way to get a boot disc for the IIe?

And how to get Oregon trail on a 5.25 floppy, I have a package of Blanks

And once I get all that, can I boot from oregon trail or do I need to put the os in first then play the game?

Apple IIc monitor that only displays 3/4 of the screen

Submitted by laurieboshell2004 on October 4, 2016 - 5:25am

I have an Apple IIc monitor that only displays 3/4 of the screen.
The right 1/3 of the display fades.
This monitor was like this when I acquired it about 5 years.
No amount of adjustment helps apart from turning up the brightness.
Further, I don't have the circuit diagram.
Please see the attached photo of the screen.
Does anyone have any idea of where to look for the fault, or what the
fault might be? I suspect the horizontal deflection circuitry but would
appreciate advice before powering up the soldering iron.

Apple IIgs monitor only displaying a single horizontal line

Submitted by jdmoser on September 26, 2016 - 12:57pm

I've already searched the forum to no avail, and I don't know the first thing to start troubleshooting this problem. The IIgs itself works fine through composite out, but the RGB monitor only displays this solitary horizontal line. I just acquired the monitor last month and have been waiting on a cable which just arrived today, so I have no idea if it's the monitor, or the cable, or something else entirely.

Help is definitely appreciated, haha. Thanks!
