Hi everybody,
I was wondering if anyone could tell me where I could find some ASCII keyboards. Specifically the old style that where used on the old Apple ][ computers and others from that erea.
Thanks again

Well, if it's an Apple ][ style keyboard that you need, why not get an old Apple ][ and use the keyboard? Apple][s are quite common, so I understand, and you wouldn't even need a complete or fully-working one.

This might me off target, but if you want to decode a standard PC keyboard, there are several options. I have written a 65c02 keyboard decoder interfaced to a 6522 and also one that uses a 20-pin AVR controller to do all the necessary decoding, providing an 8 bit ASCII output. Serial ASCII output would also be an option using a 28 pin AVR.
