Hi all --
Got myself a Seiko UC-2000 ("Wrist Information System") w/UC-2200
keyboard/terminal. The UC-2000 is a souped-up digital watch with a
dot-matrix display, and the Keyboard unit is basically a computer that
uses the watch as a display. (So it's more or less like the old
Sharp/Casio BASIC programmables, only it uses a watch for a display
instead of something built-in...)
But the watch itself is _also_ a small computer -- one can upload small
binary programs from the Keyboard unit to the watch. From the little
information I've been able to find, it has 2k of RAM, 7k of ROM, and a
4-bit CPU running at 32kHz (yes, kHz). Does anyone know anything about
the CPU? It'd be fun to write some little programs for this (assuming I
can work out how to get them transferred over...)
(See

description of the UC-2000 and others in the same family...)
