Search for keyswitch and keycap

Submitted by martin72 on February 16, 2022 - 5:27pm

Last week, I have found an Apple Europlus and I found out that  the keyswitch is broken and the keycap of character ' ? /'  is missing. So I am looking for these parts. I hope someone (in Europe) can help me with this parts. I attached some images of the broken keyswitch and I' ve removed the keycap next of this to show the type of keyswitch I search for. The last image is an example of the keycap I am looking for.

Disk II Interface Card - PROM P6 Replacement

Submitted by eggimac on February 15, 2022 - 2:55pm

HiI received a non-working Disk II Interface Card - I assume, the disk's ribbon cable was connected incorrectly… I compared the card to a working one by measuring the expected signals and swapping chips. A total of 3 ICs failed --> C3 (74LS323), B2 (74LS05) and B3 (PROM P6).

Any interest in a USB keyboard adapter for ][/][+?

Any interest in a USB keyboard adapter for ][/][+?

 

I know the PS/2 adapters are common, but PS/2 keyboards are getting less and less common these days.  Also almost all of the wireless keyboards available today are USB.

 

I've got some USB Host Modules and I'm going to try to build a prototype using an Arduino.  If I can get that working then a PCB could be designed using chips and parts directly instead of the modules.

 

Also if this works, it is probably possible to design something similar for a //e.

Apple IIGS Memory Expansion Card Chips?

Submitted by clamm on February 10, 2022 - 5:57am

Hiya folks!

 

I am curious, if I want to add extra chips to my Apple memory expansion card where would I find those chips? It doesn't say in the manual what they're called or where to get them...

 

I have the top row full, but the bottom row is completely empty. So, I believe that means the card only has 256KB on it.

Thanks everyone!
