- ...design
- David Ross coined the term ``Lizzy'' to
refer to wearable computer systems of a modular design.
Although he was originally referring to the Apple ][ architecture (as used
in WearComp2), he has recently also
come to use this term to denote the PC-104
wearable systems, as pioneered by Doug Platt. Thus the terms
``WearComp6'' and ``Lizzy'' both denote a hobbyist home-brew
PC-104 architecture used at MIT, Toronto, and elsewhere, in
addition to the earlier WearComp2 system.

- ...batteries
- WearComp2 used a 24 volt battery at one point,
after which the design was changed to operate from
a 12 volt battery. WearComp3 used a 4.8 volt battery
comprised of four large NiCad cells connected in series
and fixed to a belt.

- ...machine
- In our lab, this was located in the basement machine shop.
Subsequent to my building a PC104 enclosure from sheet metal,
others in the lab
have also been successful in also building similar
enclosures, e.g. Jeremy Levitan (see acknowledgements)
has built a couple of such
enclosures for Ken Russell, who
drew the layout on paper. Levitan was our ``local
expert'' on the use of the metal bending machine
(and on the use of the machine shop in general).
If you have never worked with a metal bending machine,
it is a good idea to find a similar ``local expert''
who has the patience to teach you this art, and
first practice on some scrap metal to become proficient
in the use of the machine. This is a simple skill to learn,
and will prove quite valuable.
