I've got a crate of them (cream colored and all black)...
Its finding a boxed, mint condition Lightpen softwae package for the
CX-70 cream colored light pen that is truly worth its weight in gold.

and they
have "light pen" ports too)
I can tell you that although the MDA card has a light pen connector, the
light pen certainly doesn't work on the 5151 monitor (far too long a
persistance). It does work on most CGA monitors
As regards machines that could take light pens. The Sirius could (or at
least there's a light pin input on the user port header). There's a light
pen signal on the analogue port of the BBC micro (I have the Torch
lightpen for the Beeb, it's not exactly simple!). The FTS88 could take
one as an option too (there's a header on the diagnostic LED board.
Obviously the GT40 does. As does the Vectrex. And I think the Atari 400,
800, etc. The Gemini has a lightpen socket (which happens to be the same
pinout as the connector between the Torch lightpen and its interfae box,
hmmm). The HH Tiger has a lightpen connector
2. Does anyone have any light pens for sale or
trade?
No, but it's not hard to make one if you don't require high resolution.
There was at least one design in 80-micro for the Tandy 1000. There were
plenty of designs for the Beeb (most of them use the Honeywell 'Sweet
Spot' devices). Thoese were not as good as the Torch one I mentioned, but
they do work.
