There were several types of card readers for the

small, fairly slow -- the CR11.
The CR11 is a re-badged Documation M200 (200 cards per minute).
The other is somewhat bigger (either
a tabletop model or a freestanding unit, depending on hopper size) and
comparable in speed to mainframe readers -- the CD11.
That's probably the M1000 unit (1000 cards per minute).
Either one would do very nicely if you happen to have
a PDP11 around.
(Or a VAX? I think VMS had support for them.)
Or an Apple ][ with a 6522 VIA adapater ;) Or Brian Knittles way cool
USB interface.
