They were mask-programmed chips.

A couple of us were able to buy the few left that Ron Oxley had early in
1998. Check with him at "Ronald Oxley <rtoxl at andrews.edu>" and see if he
has any more or can make more (small chance, but hey, it's a shot). I
bought one in April '98 to repair a good friend's unit.

Sure would hate to see it parted out. I've thought of using a different
microcontroller (one thats AVAILABLE! ;) and writing my own software for
it, but I need a non-working unit first. Seems relatively simple.

Good luck,  Chris
