//e enhanced that won't run or list

Submitted by MajorMar on February 14, 2020 - 10:17pm

I recently acquired an Apple //e Enhanced that had only a few minor issues, or so I thought. It only has a disk controller card in it and I did find one bad ram chip which I replaced. However, for some reason, I cannot run the commands "RUN" or "LIST" in either the built-in basic or ProDOS. I can load programs from the disk drive just fine but can't run any basic programs. I haven't found anything yet in my searches to point me in the right direction. Has anyone seen this before?

Early Apple II (Silver) power supplies and load for testing

Submitted by Corey986 on February 14, 2020 - 5:40am

So I am restoring an Rev-0 Apple II supply for someone. I was told it wasn't working and It was missing the power connector, so I replaced that. I opened it up (it already had screws, I know older supplies were riveted). Visually everything looked good, nothing leaking or bulging. I checked the fuse.

OK basics done before I dig into real troubleshooting.

Apple IIgs won't read anything but 5.25 floppy

Submitted by mpfjr on February 11, 2020 - 1:40am

What is the cause of this symptom?

 

Started ealier today.  My iigs now refused to see/communicate with or in any way acknowledge the existence of any drive with a format above 5.25 140k.

 

I have floppy emu.  Smartport drive is no longer working. The computer says "no device detected" or maybe it is "check startup device".  Or both at different times.

 

That is with floppy emu in 3.5" emulation mode or smartdisk mode.

Apple ][+_ Working but showing horizontal bars

Submitted by KLund1 on February 10, 2020 - 8:36pm

Hi,

  I got an AII+ that appears to be working. It seems to boot, and I can type and see moveemnt on screen.

It is just the main board with only 16K installed. No cards

But there are horzontal bars inplace of charaters.

I have a working AII+ next to this one. I have swapped EVERY chip between them. The working AII+ still words fime.  The broaken one still  shows horzonal bars.

Submitted by Fuji on February 10, 2020 - 8:39am

I'm considering purchasing a license for the (Mac OSX-based) Virtual ][ emulator as it appears to be easy and straightforward to use (as an Apple ][+) and most of it is self explanetory, but I'm having a problem getting the 80-column autoswitch function to work:

Cross posting from AtariAge's Apple forum as suggested. I'll keep both threads updated.
