[getting old punched cards read] - test-drb@ccmp.vtda.org

If we're talking about hundreds or more, you want an automated solution.
There are several companies which have sold modernish punched card
readers in the past couple of years with RS-232 interfaces on them;
the ones I see most often are Mountain Computer units which are about
the size of a 2-slice toaster and can stack a couple of hundred cards in
the input hopper.  There's both a mark-sense and a punched-card version
of this unit.

So, pray tell...  do you know what the difference is between the Mark Sense
and Punch Card versions of the Mountain Computer reader?  (and how to tell
which is which?)

I have one of these units in my collection, and even though it happily
accepts the commands which should read punched cards, it always feeds one
card and then returns an error.  So, I would start to think that it is the
mark sense version, but have never really found any identifiers on it.
