[ale] [ALE] Linux happy scanner with dual sided sheet feed?

[Tom Freeman]

Unless there is something else - I guess that I'll see what HP/Brother 
equipment with duplexing is locally available and give it a whirl.

Currently I have two Epson scanners - one works a treat after a decade 
(but no sheet feed that I can find), the other is rebranded something or 
tother, wants manual massage to get configured, and sits on the floor 
unconnected. Probably should make it free to a sympathetic home.)

I like where you are coming from, and might get forced there someday. 
Although having only 2-4 more questions than fit in the quiz may not leave 
the questions sufficiently fungible (sp?).

I kind of like that also. We were pestering the prof for a take home in 
PChem. He let us in on the take home final one of his profs handed out 
(Citedal, about 1950?). One question only. Considering the automobile, 
trace the chemical production/history from mining or butchering or 
harvesting to the final product. I _think_ those students could ignore 
dyes and pigments. Not only take home - but open library. I'm not certain 
how close that instructor graded that pile of paper, but it would take 
time.
