Griffin iMate ADB/USB Adapter
With clicky keyboard being all the rage these days,, many have picked up older Apple keyboards, as opposed to dropping serious money on new hardware.
The Griffin iMate ADB/USB Adapter makes using a keyboard like the Apple Extended II easy to do. This adaptor will accept an ADB cable on one end, and plug right in to a USB port on the other — even the USB 3 ports found on Apple’s new MacBook Pro and Air models. The Mac will never know the difference, and you can type as loudly as you wish, on hardware that hasn’t been made in over a decade.
