How is this relevant?
I'm adding something to the conversation, I have previous experience doing basic microcontroller programming, I found a pre-existing example of what I'm looking for, some documentation in Japanese... While I realize all of this is several years old and likely discussed elsewhere -- no, I did not attempt a search of the forums, though I have done some fairly extensive Googling at this point -- it's relevant to what's going on here, in this thread. I read through your NeXT keyboard thread as well, but nothing new was added there. In it you assumed the board you got was PS/2 when in fact none of them are (and yours was non-ADB, making an off-the-shelf converter unavailable); someone made mention of the converter I independently found and you immediately shrugged it off. I do realize you never intended to use the board, just harvest the keycaps, but still.
How do my posts have any relevance to your "theory"? This is not as case of asking to be handed things or otherwise being lazy, I'm sharing my findings in hopes they will be helpful and draw the interest of others. Your posts in this thread, on the other hand, have been consistently negative, added nothing, and shown a total lack of interest in progress. If that's the extent of what you're going to "bring to the table" please, spend your time elsewhere.
EDIT:
To clarify, I'm not expecting someone else to do it, I'm going to do it. Myself. I have done more complicated things, both from an electronics and programming standpoint, in the past. I'm just looking for the necessary documentation at this point.
