	I know Greg Priest-dorman uses his for extended periods (as he
will doubtlessly be able to confirm) and the tiny text is quite usable
when "assisted" by speech like emacspeak.

	The M1 tech briefs at www.tekgear.ca have the answer.  You can
feed it with 9-15V (I believe) or you can supply it with +5V directly by
opening it up.  Details on the tekgear site.

	SVGATextmode shouldd do it.  Lots of modelines on Greg's site as
well as tekgear (who has linked to Greg's modelines, I believe)

	Never tried it - Anyone?

	I have not yet been able to get Xwindows working on the crappy
pc104 vga board I got, but I am still trying.  It does support X though.
Steve Mann had a post a while ago with glinaccess which, among other
things, provided large-font x terms.  I use it all the time.

	But of course!

	I have since updated the design and have some new pics to put up
sometime.  If you'd like to make your own version, let me know and I can
share some of the things I learned which may make things easier.
