2 things -- why would you need an array for a nipkow device, since they
are supposed to use a single modulated source per display? Unless
you intend to build an array of linked displays, like Rehmi did. (4
displays
"on top" of each other, all on the same disk)
And, shouldn't the array used by the P4 be available somewhere,
commercially? Perhaps as a Nintendo Virtual Boy repair part...
BTW: I took apart my VB, and the two displays are utterly independent,
physically. Electronically, they are both fed from the same board, which
implies that if there is a link it is probably the sync signal from the
driver
board. Nothing else, including the display information (displays are
independently addressable) is common to them both.

It's actually a pretty good machine for any time. I wish someone
would produce a pocket version of the M100 -- the Game Boy is
a Z80 based machine, so it's "close."
The whole thing could fit into my phone number "organizer," and
still have a decent keyboard.
Doesn't seem like it'd be too hard to produce a "programmable
organizer" device, based on the M100.

Of course -- but Win95 is so pathetically inefficient, and ridiculously
bloated, that I can't stand using it. W98 is slightly more efficient,
but still just as bloated.

Actually, tomorrow is the last day of my assembly course, other
than the final exam, at least.
