apple portable keyboard

Hi I use the case of my portable with new macbook but I want to keep the original keyboard, do anyone know how can I use the macintosh portable keyboard and change the IDE interface to USB so it works with new Laptops?

It's not an IDE interface, it's a simple as it gets. The ribbon cables connect the key matrix circuit board's switch actuated connection as they'r made to a controller on the motherboard.

Unit much like the Portable NumPad



4x4 jeyswitch matrix



Controller output to LCD display



You'd want a controller that outputs USB, such should be available off the shelf.

If you have a KBD you don't care about or can get your hands on a dirt cheap PS/2 KBD, tear it down and examine the membrane switch matrix/controller setup to get an idea of what's going on in there.

Interesting project, definitely a hacks forum thread.

Couldn't find more than simple 8x8 matrix controllers in a quick search of Codemercs website. KeyWarrior was a powerful controllers that handled USB, ADB and PS/2. keywarriordatasheet.pdf

Hadn't given this one much thought, but it looks really promising. I'd like to check it out, link?

PHoto at top a prototype and this one a production unit?

If you're up to trying that one (if they become available again) it'll probably work. Depends on electrical compatibility of the keyswitches and key count, which appears to be higher than the Luggable's.

De nada, looking forward to seeing your project progress. Please post your research. I've got a couple of KBD projects to mess with as well. One approach is to try the controller from an AEKII on a mechanical KBD and a membrane KBD with an AppleDesign controller. My parts Luggable recase/mod project will be following in your footsteps. it will be interesting to see if my NumPad matrix maps to the main board or is a discrete matrix.  If the latter, it can be a programmable pad.
