Edge punched cards

[FJGJR1 at aol.com]

Hi!
 
Don' forget about the  edge punched cards of "McBee Keysort Cards" so  
popular in the 1960's, at least in the USA!
 
I still have a box of them in our basement waiting for the dumpster.   Sure 
brings back memories of how things have changed so much in managing data on  a 
personal basis.
 
They really helped me with my Ph.D. thesis in organic chemistry with  respect 
to all the references for doing the research and also for writing the  thesis.
 
I think I saw someplace on the internet a  few months ago that  someone was 
interested in them.  If I recall correctly, they were possibly  thinking about 
some sort of automated system of accessing them so that the info  could be put 
into a computer.  The cards were from sort of past big  project.
 
So you may want to do a Google search and see what you come up  with.

Thining  of edge-punched cards...

The original membership cards for the  Cambridge University Computer 
Preservation Society had 8-level paper-tape  punchings along the bottom 
edge giving (IIRC) 'CUCPS' (im ASCII),. the  member's computer userid 
(ditto) and the membership number (3 bytes,  binary).

I don;t think anyone ever tried to machine-read them  though.
