Hey Joseph,
No likely. The 40H244 CMOS chip won't source much current, even if you
could keep all 8 of the output drivers on. But you can't because those
signals are also used for the keyboard scan logic.
And the only other outputs there have large pull-up resistors, also
preventing much current draw.
Your best bet might be to use the BCR port on the side of the unit
instead. It has a 5V output that could be used, plus a 9-pin DIN
connector for support.

Kenneth - Do you think you could pull power from the printer port? I mean if
you going to make a mount then might as well have it power the light as well !

Hmm, yep, I think you are correct.
In that case it would be a 26-pin Dual Row IDC connector:

Isn't that connector for the printer side of the cable ? I assumed he was
thinking of the back of the Model 100.

Yep, it is a 36-pin centronics connector:

I was in the book store yesterday and picked up one of those little
battery-powered lights that clip onto a book. Not the ones with the giant,
scary clamps, but one with a smaller, dainty clip.
I thought I might have it do double-duty illuminating an M100 screen from
above, but there doesn't appear to be anything suitable on an M100 to clip it
onto. Then I thought, maybe I can plug something inert into the printer port,
like a very short, unpopulated circuit board. (The serial port is occupied
already.)
Can anyone tell me what the connector for the printer port is called? I assume
that once identified, I can buy it online, since I'm a long way from the
(last?) Radio Shack in Wisconsin Dells.
