Re: mechanicals for an open voting system

Hello:

Don't forget that you need to build some sort of
printer enclosure. If you will dig down into the
correspondence archives, there was considerable
discussion about this issue at one time. The basic
enclosure has to accomodate a number of different
printer designs, be able to be opened in case of jams
and vandal resistant. Also, the printer, along with
any other enclosure, has to be designed to accomodate
tamper evident seals for election day.

I cannot emphasize too much that this equipment has to
be user friendly and the typical user will have a very
low amount of mechanical apptitude. You might want to
study the kludge printer added to the Diebold TSx in
California for things not to do.

Thanks, Ed Kennedy
