Lisa 2 Keyboard/Mouse substitute?

I happened across a Lisa 2 (Model A6SB100) this past weekend...Seems to be in fair (restorable) shape. The nicads on the I/O board are corroded, but that's easy to fix. Unfortunately, the Keyboard and mouse are missing. Does anyone know if I can substitute a keyboard and mouse from an early Mac? (the ones with the non-adb keyboards and db9-connector mice). I don't mind hacking the connectors, if someone can give me the pinout info. As far as I can tell, the lisa uses some sort of mini-db9 for the mouse, and a 1/4" headphone-jack for the keyboard (weird!) If this isn't possible, I'd appreciate any hints as to where I might find a lisa keyboard/mouse (be nice now! :-) This critter also came with an Apple Profile (model A9M0005) external hard disk that seems to attach via a db-25 cable (to the lisa's parallel port?) I noticed that one of the pins on the lisa's parallel port connector(db-25 female)is blocked with epoxy (probably to prevent people from connecting a serial cable to it). Can I simply use a straight-through db25 cable (with the blocked pin removed) to connect the profile to the lisa, or did apple use some sort of proprietary wiring scheme? -Thanks! -al -acorda(a)1bigred.com
