If anyone here does get one, I've got a simple Arduino UNO program that
interfaces to the parallel output and sends fully decoded information over
USB at quite high speeds. The M-1000-L is a great reader, very reliable,
and easy to work on too (I did a little routine maintenance, but mine was
in 100% working shape when I got it).

Here's a video:

I'm also working on getting a cable made to hook up to the M843 CR8-E
punched card reader interface for the PDP-8/E, but that's a project for
another day (year?).
