I've seen advertisements for non-standard keyboards that have like four keys per hand, and you use some sort of binary-like sequence to select the keys...you know the type... Has anyone a clue on how the keys are assigned, and how you get a full character set from them? I'm thinking either a hardware hack, or maybe faking out a normal keyboard into working that way by leaving your fingers on the asdf jkl; keys... Robb Pfister_Rob%dneast.dec@decwrl.dec.com

The one I've read about (the WriteHander) is done like this, I think: the 4 fingers hold down (or don't hold down) buttons for the lowest 4-bits of ASCII (digits 0-9 come out in binary). Then the thumb presses one of 8 buttons for 7-bit ASCII, or one of 4 buttons for 6-bit (old, uppercase only) ASCII. The finger buttons are only read when the thumb button is pressed, so you set the fingers and strobe the data with your thumb, then set up for the next char. This is from very old organic RAM, so don't blame me if it's wrong... --- Merlyn LeRoy
