What are the possibilities of attaching a keyboard other than the one supplied to a Mega? What kind of signals are on the keyboard port (or is it <gasp> hard-wired)?

Replacing it with an off-the-shelf keyboard would be an interesting exercise. The keyboard is much more than just a lot of switches and a decoder, it's really a micro- computer in its own right. If you never planned to use your Mega keyboard ever again, you could rip the electronics out of it and try to attach another keyboard, but it would probably take some effort to match the scancodes up properly. (You'd probably want access to an EPROM burner so you can generate a new scan table...) Note the same applies to a regular 520/1040 keyboard, just that it's all in one case instead of at the end of a cable. -- / /_ , ,_.
