I am going nuts trying to get a keyboard working. I followed directions I found on Aminet and ended up with apostrophes flying across the screen, after some hunting I learned that this means the clock and data lines are reversed. I switched the lines and the flying punctuation stopped but there is no response from the keyboard. Keyboard works perfectly on a 3000, so what did I do wrong. HELP
thanks
Hi,
Can you give us a bit more information?
Which directions did you follow on Aminet?
/hard/hack/a500key1.lha is probably the easiest to follow, even though it is written in Spanish. Requires a couple of trace cuts on the under side of the board, which is preferable to mangling the legs of your PLCC chips which some of the other mods advocate.
If you are getting the continuous stream of ''''''''s then
the power and ground signals must be connected ok.
Double check that you have indeed swapped CLK and DATA, because it should just work from where you were with the '''''''''''s.
