OK, I'm thinking of doing a wierd mod on a VT100, just how much room
is inside one of them? I need room for a 7 1/2" x 9" x 2 1/2" board
(the 2 1/2" is thanks to the heatsink and RAM), and would also like
to be able to fit in a smallish 250W PS (3 1/2" x 5 1/2" x 6"), and
a 3 1/2" HD.
I've put two photos of a topless VT100 in http://vt100.net/zane/ which
might give you some idea of the shape of space available.
On the left hand side of the photos you see the card cage. The space
there is 10.5"H x 10.5"D x 3.25"W (but only 2" unobstructed to the
back). You might be able to make that 2.25"W to the back with a bit of
persuasion.
The PSU occupies the space at the back of the terminal, but only extends
halfway forward, so there is space underneath the flare of the tube of
10"W x 4.75"H x 5"D. Of course you'd not want to disrupt the picture.
(Memo to self: must sort out vertical linearity on mine!)
At the back right hand side (again, as you look at the picture),
underneath the high tension wire to the tube, there is a space 4"W x
3.5"H x 5"D.
