Apple IIc Plus & Karateka

Hi there

I have three Apple IIc Plus machines, and while Karateka runs, the graphics in game is corrupt and unplayable. The sake disc plays on an Apple IIe Platinum. 

This happens across all three of the Apple IIc Plus that I have, so they can't all be fault.

I am guessing there is a version of Karateka that will work on the IIc plus or perhaps not.

Anyone else come across this with that game?

Other games I have tested work well.

 

Thank you.

Maximum acceptable resistance in IIe key switch

I bought a supposedly tested and working numeric keypad for my IIe. And of course it's not fully working. Half the keys don't work. Opened it up to find that someone spilled coffee or coke in this thing 30+ years ago, and it never got cleaned up. I desoldered all the switches and started tracing out the PCB. Looks like I'm going to have to make 12 bodges.

#FujiNet for #Apple2 bring-up status report 2022-04-10

@jeffpiep has been hard at work getting the #Apple2 CONFIG program for #FujiNet in place, and it has reached a very usable state, already. I wanted to show a typical usage session loading disk images off the Internet. Enjoy.

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
