Apple IIe Astec AA 11040B Power Supplies

I have a pile of Apple IIe's I'm refurbishing, and I just ordered a bunch of cap kits from Console5 to recap the power supplies, most of which are the Astec AA11040B style.  Iniitally, I discovered all but one worked properly, so I was a bit surprised to see varying behavior when I started the recap process.  Specifically, several would provide the +/-5V and +/-12V outputs when powered on.  Others simply made a repeated ticking sound, a symptom I've come to understand is often a capacitor issue - such was the case when I worked through a few IBM power supplies.

Apple Europlus

I try to repair an Apple II Europlus and the only thing I get are some vertical bars at the screen. No beep and the keyboard doesn't respond. Where can I start with troubleshooting? Is it possible to start the Apple without a keyboard?

Apple II & III Xebec and Streamer cards

Hello,

I got these two cards from an auction and I think they come from the same pc. I believe one is a Sasi (scsi) card to interface a xebec HD and probably the second one is intended to interface a tape drive. I have no clues about where to find docs or sw for them. They are both from HAL manufacturer. Does anyone know anything about it?

Thanks

Floppy EMU -- Help

Hey guys,

It's been like many years since I fired up my Model A (SD Card) and Model B (Micro SD Card) Floppy EMU and for the life of me I cannot get any DSK image to boot.

SLOT 6 is my card and 1 ribbon cable off the top going into an AB switch which sends to a to physical drive and the Floppy EMU.

None will boot. Floppy EMU recognizes each DSK image but it won't do anything when I power up the Apple II. The mode says Apple II on the Floppy EMU when it starts.

IIe Joystick Issue

I know most games don't fully use the analog nature of the Apple joystick.  But at least one game does (Conan - you can either walk or run) and its not working right on my IIe with two different joysticks.  Anytime I try to run right by pushing the joystick all the way, he never goes faster than walk speed.  Which actually makes the first level impossible, as you have to jump a gap with a running start.  I have 2 different Apple brand joysticks, and neither work right with the IIe and Conan.  They do however work fine with Conan and my IIc and IIgs.

Troubleshooting Microsoft 16k Ram card

Hi

Testing a Microsoft 16k card in a known working Apple II Plus.  When I plug it in and attach the ribbon cable the machine will not start - no beep to action.   Thoughts on trouble shooting this?

 

If it was a ram problem I'd think it would still start.  There is one cap on the board would that prevent the computer from starting if it were bad?

 

TIA

Michael

Quick Disk II 13/16 Sector Question

I recently came across the 13 sector ROMs for a Disk II Controller Card and thought I'd give them a try.  But before I do, I wanted to know if a 13 and 16 sector card can peacefully coexist on the same computer?  Or would I need to designate a separate machine? (not my preferred solution since there's not as much out there in the way of 13 sector software)

 

 Obviously, the 13 sector ROMs would be on different a card than the 16 sectors and in different slots.  So I think it should work?  But I want to be sure before I risk frying something.

How I Fixed My Super Serial Card

TL;DR version:

  • My Super Serial Card wasn't accepting any keyboard commands, either via Control+A or Control+I.
  • Attempts to transfer anything over to it just resulted in garbage, if anything, on the screen.
  • The problem turned out to (probably) be worn out DIP switches that no longer closed the circuit when set to "On".
