Humm... I don't remember the one I am thinking of
having an interface
box. I think it just had a mini-din 8 to 1/32" phono plug that plugged
into the side of the watch.
Here we go. From Tidbits #36:
"Neatest Product: The WristMac, from Ex Machina (published by Microseeds
Publishing), is a Seiko wristwatch that stores up to 80 two-line
"screens" of data, such as phone numbers, appointments, and to-do lists,
complete with an interface cable that connects to a Mac serial ports, so
you can use the included HyperCard 2.0 stack to enter and manipulate the
data. You can even have the watch's alarm function alert you of the
appointments that you've entered into the database."
Here's a pict: <http://www.tcp-ip.or.jp/~danbo/WRISTMAC.html>.
The biggest difference appears to be that these use a serial interface
like you say, while the UC-2001's that I have use a wireless connection
with an interface box.
