Apple IIe Platinum seems dead - help!

Submitted by mabalmer on January 1, 2021 - 10:08am

I was recently "gifted" an Apple IIe Platinum -- with a dead power supply, and every single slot empty. 

The power supply had significant damage to it (likely from whoever owned it previously replacing the fuse on the AC side with a piece of 14-gauge wire) and had the 6-pin motherboard power plug clipped off.

Apple 2 color monitor pcb

Submitted by medwardl on December 28, 2020 - 8:37pm

I'm trying to resurect my Apple 2 color monitor, the pcb is pretty close to beyond repair without a mess of bodge wires as some of the traces have disintagrated and the rest isn't much better. Does anyone know where I might get a reproduction pcb or a file I can send to a pcb maker and have them make a new one?

Apple IIe plug and socket partnumber

Submitted by martin72 on December 25, 2020 - 5:22am

Hi, the connection of the plug and socket from the power supply (6 pins) to the mainboard (J14) of my Apple IIe European version is unreliable. I am looking for the part-number or type of this connector and socket so I can order and replace them. 

Does someone know this information or where I can find a replacement for this?

Have any of you seen this symptom before, and if so, what culprits would you suspect?

14.31818MHz Xtal - What Pico-Farad Rating?

Submitted by Timelord on December 23, 2020 - 8:46am

Apple helpfully marked the xtals with their own p/n, 197-0001. Does anyone happen to know what Pico-Farad rating is correct for buying replacements? 18pF?

 

Are there any other ratings that fall into a narrow range that I need to stay within? I'd like to order a reasonable supply, rather than one piece, to have on hand, and I'd rather not experiment with tolerances. 

 

Looking at http://www.willegal.net/appleii/appleii-components.htm, the system is extremely selective in what will work properly.

Apple III, only Apple II emulation works

Submitted by achim_boers@mac.com on December 22, 2020 - 8:40pm

I need some help with my Apple III. Apple III disks don't start, only a very few work actually.

Strangely the Emulations of Apple II work, The Confidence Program works, and Atomic Defense works, but none of the other disks.

The Machine is futher in working order, with the keyboard diconnected the RAM looks to be OK.

 

The Confidence Program gives a Machine Status:

Memory Map good for 128K, although it's a 256K machine and has 256K installed.

Disk drives all checked and the Interrupt System all checked as well.

Looking for SW and libraries for A.U.G.E. clock

Submitted by tokabln on December 22, 2020 - 1:10pm

Dear folks,

 

I'm actually having an A.U.G.E. clock for repair action and do need some SW as well as libraries to be able to test the card right after having finalized the repair actions.

 

I know that there is some stuff at the Apple-Box from Harro... but this did'nt help me here. So if someone is having such card and some relevant software I would appreciate if he/she would share this information with me.

ProFile Cable: Need Reminder, Is it DB25 Straight Through?

Submitted by Timelord on December 21, 2020 - 11:25pm

I am pretty sure that the cable for the ProFile is DB25, wired straight through, male to male. That is from memory of the last time I had to replace one, in the mid 1990s. Can anyone confirm this?
