Boy, can I relate to *that* one! As part of the preparations for an
exhibit (that I am *still* working on) I needed to find a quantity of punch
cards (unpunched) to feed to my unit-record equipment and mini-computers.

I chased that one for a *long* time, getting a partial box here and there
from people usually using them as notepads. I finally stumbled into a
decent quantity from a local recycler who had heard of my search. Turned
out that he had just cleaned out an old data center that had been relocated
and found a couple of pallets of them! (salvation!) I grabbed about a
dozen boxes. Don't know if there are still any left...

To a PC? Probably, but seems somewhat sacreligious. (and excessively
complicated) I've actually hooked up a DEC card reader to one of my
Altairs for a recent job while I was still restoring the PDP-8 that it
actually should have been hooked to. Took about 4 hours to wire the cable
and interface, and another 1.5 hours to hand assemble the code to run it...
