Digital BW, The Print

I am finding myself scanning MOSTLY 120 film.  My old Agfa DuoScan is 
doing just fine for most things, but I get curious.  I recently ruled 
out the Minolta equivalent to the Nikon 8000 since it won't operate 
with Win98se.  Since I have 512 in memory, I couldn't use, or often 
need the extra dpi of the Nikon since I can't process it.

Therefore I start to get interested in the Polaroid.  I've seen 
suggested retail around $2700.  Seen used about $1000 under that, 
which seems reasonable.

I saw Bruce McElhaney & Jeff Greer use the P.SS.120 and would of 
asked them offlist but didn't keep the digests for email.

Does the film carrier pass all the way through the scanner?
I'm shooting a 6x8 back (~75mm) on an RB Pro-S...am I going to be 
able to fit that into a carrier?  I'm sure I have other questions & 
will lookd at the info at Polaroid...Nuances are best reported from 
users though.

Thanks,
Cleavis
