If I can find the MagCard manual, I'll see if I can find the capacity. I
don't know if it mirrored the punch card or not, although I think it
held more data. They were supposed to be terrors to run.

I think you're right. You are the second person
to ID the cards as from an early memory typewriter. I should have mentioned in my earlier
post that each of the cards was paperclipped to a carbon copy of a document. Based on the
length of the documents, these cards didn't hold much.
I have posted a scan of a couple of these cards at
http://home.earthlink.net/~wmsmith/_uimages/IBMCards.jpg to the extent that it helps in
further IDing them.
Thanks.

Sounds
like a magcard, probably from an old MagcardII typewriter or a
Displaywriter.

The cards have what appear to be track marks on them in three parallel rows on the
horizontal, as if fed through a reader.
Thanks. If it would be useful I post a scan of one of these.
