The Poma/WIA display is just the Shimadzu display
http://www.spi-inc.com/dataglass/

Hitachi still has their site on it
http://www.hitachi.co.jp/Prod/vims/wia/index.html

That takes normal analog VGA and 5v. The Pomo may do the same thing. I
thought it was discussed here before but can't find anything in the
archives.

This is the wiring for the other Xybernaut display, which of course is
completely different. via the wayback machine
