Apple II

Hello! I'm fairly new to the Apple II community. I just purchased an Apple IIc locally, but it did not come with anything but the unit itself, so I'm in the process of starting from scratch gathering peripherals or making my own. My hardest struggle is figuring out a solution for a mouse to use. So I've set out to find/make an adapter to use a mostly modern PS/2 mouse to interface with the 9 pin AppleMouse jack.

Does anyone have any thoughts on what might be holding me up? Is the Arduino code for the quadrature conversion the correct method? Is there a better way to test a mouse input on the Apple II or a better way to acknowledge it's being read by the machine? Some help is greatly appreciated!

This is a long shot...

I'm looking for the General Logic Unit (GLU) chip for the Apple IIc Plus.  

It is labelled as part number 342-0243-A and is a PAL20X4 gate array chip, and is indicated on the IIc+ motherboard as UE9.

As shown here:  http://www.applelogic.org/files/3420243A.png

If anyone can help either supplying a replacement or has the code to program the PAL20X4 with a programmer (assuming you can still get one of those blanks) I'd certainly be grateful.

Xdrive firmware has been updated to V1.03 which addresses a couple of issues:

1. Images created on Windows machines would sometimes show incorrect long filename.

2. Using the N command to boot disk in lower slot did not work with CFFA.

Happy Sunday!

Looking for help finding documentation for the Know Drive from Abacus Enterprises in Detroit MI.    I've come across a Know-Drive and the attachment seen in the images.   I can not find any documentation or software for this - but would so much love to play with it!

I've found references to it, articles about it but not documentation - there has to be someone out there who has the software and/or documentation for this - any help would be greatly appreciated.
