It has nothing to do with any other reasons to not get
a scanner (of
which it sounds as though you have plenty), but you do not necessarily
need a "modern PC". I've got at least one scanner which speaks
SCSI...or is that enough to count as "modern" to you? :)
I haev no moral objections to SCSI at all (it's fully docuemtned, it's
not over-complicated, there are standard ICs to talk to it, or you cna do
it all in simple logic chips, etc). The problem is that very few of my
machines have SCSI interfaces.
Also, for a machien to be useful with a scanner, I would have thought it
should have a high resolution graphics display. Of the machines I use,
the PERQ probabl;y has the heighest pixel count (1280*1024),. but that;'s
only 1 bit per pixel. The I2S units have a better colour resolution, but
only 512*512 pixels. They conenct to a PDP11 (or will do when I get round
to restorign them).
Of course the problem is that there are not likely to be any drivers for
a scanner on any of these machines. I realsie the scanenr commands are
documented (at least for some scanners), but writign the drivers is not
something I want to undertake....
