6809 Cpu's

Submitted by gsmcten on October 8, 2016 - 6:22pm

Ok.

I have an opportunity to pick up two complete
6809 CPU Kits.

There are several threads concerning 6809 CPU's
already up here, but I want folks to weigh in
with their honest opinions on the actual usefulness
of these Chips for the Apple II.

Right now the Seller in question has these two
kits set at $150.00. Is it worth it?

And once I get them (if I get them)what can I do
with them?

All comments welcome.

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.
