I seriously doubt it. The keyboard for the original Macs used an RJ11 type connector. The SE/30 uses a regular old ADB port. But anything is possible, I suppose, if you have the determination and know-how. How handy are you with electronics and soldering irons? Can you tell the difference between a resistor and a 555 timer chip?

About 10-15 years ago, the local Salvation Army store had a whole pile of these things. I had absolutely no interest in them. Now, the Salvation Army doesn't accept computers anymore. Probably because of stuff like this. Weird, huh?
