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.

Virtual ][ (II/II+/IIe emulator for Mac) beginner issue

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:

copying DOS-Master image

Submitted by namachari on February 2, 2020 - 9:05pm

Hi All,

Many years ago I created a DOS Master 1.7 image for use with my CFFA (Not CFFA3000) card. The initial setup of the image was done by Vince Briel, but I extended it to contain 100 DOS 3.3 games, and changed the splash screen to be all caps for those with ][ or ][+ machines. It took me quite some time to collate everything, as you can imagine. However, in the end my disk image was somehow 64mb in size, and not the standard 32mb partition size. I think I maybe made a mistake somewhere along the way, possibly with Ciderpress.

Removing the AMP power connector from the power supply wires

Submitted by Corey986 on February 1, 2020 - 5:53pm

Is there an easy way or a special tool like they have molex
Pins to remove the wires from the AMP power connector on an Apple II supply? I have to transplant the connector from one supply to another and don’t want to break anything.

Thanks,
Corey
