Why? it's not going to take much effort to drive the displays - they don't
have a bunch of pixels, just 3 stripes on them (at least the one I've seen).
You could probably pack enough electronics in half a dozen transistors, to
control the beam in the CRT (excluding the HV source). Usually, the whole
thing acts like one monitor - one input signal to the whole device, whether
it's NTSC composite video (unlikely) or RGB at some fixed (NTSC maybe)
frequency.
It wouldn't be a whole lot more complicated than an average TV or multi-sync
monitor, other than having a larger power draw, and HV supply. :)

I would have liked to see the multiple CRT one
redone with
software/firmware to present a portion of the image on each screen.
(I want a multi-Giga-pixel display!)
I wonder how much a 2" CRT costs in bulk.... of course after the
glass, you have to have a frame buffer and video driver for each of
them.
