More flexible hardware. Someone who shall remain nameless (Hi, GP-D! <G>), wanted a BAT keyboard clone. I had a disabled girlfriend at the time, and was thinking of having her able to type with some custom other keyboard (head switches, etc.?) We got the idea that, if we made a machine that could connect to <most any set of switches, or a smart controller, or another serial device>, and be taught to translate that to an AT / PS/2 data stream, that we'd have a GOOD tool for wearable computer users. Want a Bat? Just plug a Bat keyhead in. Want a Twiddler clone? Plug that keyhead in instead. Want to try out a ChordKey, a Bellaire keyboard, a DataHand keyboard, an AccuKey, a Minimal Motion Access System, or a DataEgg? You just have to make a keyhead that does the switches, and leave the rest to the innards. We figured that's a LOT better way to go than having 37 different projects all with the same basic purpose. One whole abstraction layer between the keyhead and the Keydlers' innards. Another benefit is that they keyhead's lighter - and if you drop it, no electronics are broken, as they're all right next to your wearable. I've worked on the thought a bit while Tim's been busy, and now that I'm getting into pottants, I should eventually be able to make cases <G> If the keyhead can store the "here's my identity and how I work" data, in a small cheap $2 IC, this should really work well...

I may go to C if I can set it up quickly. Reason we moved to Atmel parts is that then C would not be too slow; with 4x the speed, coding in C saves a LOT of coding time.
