That's mostly a matter of will. There were
several interesting
applications (such as VEDIT) ported to the Displaywriter.
That is a good point. The only argument that I'd have with it is
that since so much of the software we'd find interesting was
ported from general-purpose platforms, the particular machines
aren't really a part of it.
As far as
architecture, an old AES 800 WP is about as exciting as architecture
of the time gets--a custom ECL CPU supported by several 8080's doing
the peripheral I/O. I'd love to own one of those.
I would too. That's a good example of the exceptions. I guess
I was thinking more of the later generation devices. So many
of them were just Z80s or 80186s with pretty conventional
video and disk controllers. Not really any different from many
general-purpose designs of the era, but much less hackable.
But as you point out, there are certainly gems to be found in
every corner of the computing world.
And let's not forget that "computers"
like the QX-10 weren't all that
far from being word processors, what with integrated Valdocs and
whatnot.
But is it really the WP aspect that makes it interesting or the
form factor as an evolutionary step to PDAs? I'd even
suggest that there may have been something of an unholy
marriage between those little things and the suitcase
luggables that built the image of a laptop in some minds.
