Apple IIe Keyboard Issues

Submitted by zippyedge on February 7, 2021 - 12:10am

Hey guys,

I recently got myself an Apple IIe and IIe Platinum locally. After cleaning the keyboard PCB with 91% alcohol, (1-9) on the keyboard no longer functions, though everything else works. I also tried the keyboard from my IIe Platinum and can confirm that nothing is wrong with the motherboard/keyboard chip. I also have a spare II Plus, that I may be able to get parts from. Any help would be great!

 

Thanks,

George

Apple II IEEE-488 Interface Manual

Submitted by brimars on February 6, 2021 - 8:52pm

I recently acquired an Apple II IEEE-488 interface manual in English (Asimov version is German). Does anyone have an interest? I haven't scanned it yet but if there are interested folks I'll increase the priority on it. Since I have about 2000 projects banked, that should have it done by 2035. I'm actually interested in using it with my IIe Platinum but haven't got the space just yet to hook things up and haven't created the adapter cable for the card...

ImageWriter II Carriage Grinding/Jumping

Submitted by nick3092 on February 5, 2021 - 2:46pm

I have an IW II that I've been messing with trying to get working. Every time I clear one issue, another seems to pop up. The current issue is that randomly while printing, the printer makes a grinding noise, and the printer seems to lose track of where the carriage is. So then it starts printing lines horizontally offset compared to where they should be.

Does anyone have a dump of 344-0033-B? It seems to be an updated version of the 344-0033-A ROM $00 that is commonly available.

Resurrecting an Apple //e --- Part 2 --- The DuoDisk Drives

Submitted by KimKimberly on January 31, 2021 - 10:42pm

I thought maybe it would be best to create this "Part 2" so the sub-topic of DuoDisk would be easier to find and maybe someone in the future would be helped by following my progress with each part of the //e  resurrection.

 

Part 1 - The Power Supply is here: https://www.applefritter.com/content/resurrecting-apple-e.It started to divert a little from just the power supply (with some pretty good tips and advice about dirty disks), and some other folks discovered the same capacitor fix I did (again with great help from the folks here) so it's still a good read for that.

Ortho Personalized Plant Selector

Submitted by brimars on January 31, 2021 - 7:41pm

Several years ago I purchased a number of vintage computers  (in very poor condition) with a few hundred disks. Most are damaged to some degree but one stood out: Chevron logo, Ortho Personalized Plant Selector. Has anyone run this program on a real IIe? I can't get it to run either by booting or using a ProDOS boot disk separately on my IIe Platinum. I also have an unenhanced IIe but it's a pain to get it hooked up so I figured I'd see if anyone has run this.

16p to 9p Joystick Adapter

Submitted by Timelord on January 31, 2021 - 7:22am

I have a few of these, and before I use one, I just want a reminder. Should the red stripe be on the front (toward the KB), or away (toward case back)?

 

I will likely do a pinout continuity check ere using it, but I figured I would ask before I spend that bother. I think that pin 1 is the lower-left pin on the internal connector, but that is from memory, which tells me that the red stripe should be on the borrom, towared the KB. I suppose I can connect it and check for vcc on the right output pin; probably the easiest way.
