I'd been looking at either a modern keyboard such as a Pok3r or something vintage like an IBM Model M. Something I didn't realise was Apple also used to make mechanical keyboards — right up until 1996 when they discontinued the Apple Extended Keyboard II. The Apple Extended Keyboard II, or the “AEK II” was introduced in 1990 as a. The AEK II was sold until 1995 along with Mac desktops like the Macintosh IIci.
Hi, I just obtained an Apple Extended Keyboard II from eBay, and I'm trying to use it with my late-2008 MacBook via a Griffin iMate ADB-to-USB adapter. Unfortunately, it's been giving me a bit of trouble. At first, the letter 'q' would be randomly inserted, even if my fingers had gone nowhere near it. When I tapped 'q' itself, it would repeat 10 or 20 times and then stop, even though I was not holding down the key. Thinking that I perhaps hooked the keyboard up incorrectly, I switched ends of the ABD cable. Then some keystrokes began to not register. For example, when I tried to type 'this' at speed I only got 'thi', and would have to repeat the 's' for it to register.

Typing it slowly produced better results. I do not believe that it is software-related. I tried the keyboard with a friend's year-old white MacBook and encountered the same difficulties. As this is the first mechanical keyboard I've owned, I'm not quite sure how to go about figuring out what's wrong. Might a good internal cleaning help?

[Clean and Repair your Mac keyboard: How-To Guide|.html] Vacuum up dust between the keys, or blow out with compressed air designed for electronics. Actually my first action is just to turn the keyboard upside down and shake out the crumbs. If necessary you can pry off the key covers with a screwdriver. If you're lucky one of those will have become misaligned and it's an easy fix to reseat it correctly. If you're unlucky one of the contacts is faulty. You can probably find more detailed instructions for that particular model if you search the web for, 'Apple Extended Keyboard II clean repair'.
