That is neat. I think I vaguely remembered hearing about it. Never seen it working before. Much nicer to have a video than 10 year old press releases from Pakistan.

Very cool that you had heard about it. I think I have some additional pictures of proto boards and alternate industrial designs. Will try to dig those up and post.
 
Some additional pictures:

The early proto of the dev board - note the keyboard built from scratch from an array of push switches.

Very nice! It's not often you see the 8051 in an application like this.

Um, got any spares you're selling? :)

Sadly, no spares. I am just glad the Mountain View CHM is preserving it. And you are right, this was a rare app for the 8051... three 40Mhz RD89C51s working in concert, to be specific!

I have one lying around somewhere and if I can get my hands on a running system I would like to do a better video in future.
