Which connection?
When ordering hardware to plug into your computer (such as switch interfaces, keyboards or mouse alternatives,) you may see a range of options for cables or connections. If you are unsure of which of these you need, check your computer to see where the keyboard or mouse plugs in, and match it with the pictures below. If you need any help choosing, please do not hesitate to call.

ADB connection – found on older Macintosh computers. New Macintosh computers will not have an ADB port. Used for old keyboards and mouses.
If you have a Macintosh computer with an ADB port it may be possible to use an iMate converter (made by Griffin, available through your Apple dealer) to plug in a USB device. However, before purchasing a new device for an old computer we suggest that you check that the computer has enough memory to run the new device.
