KIM Manual / Selectric

The IBM MagCard and MagCard II used the selectric in an interesting way. The
MagCard II was a large (and HEAVY) box connected to a Selectric II with a
very thick cable. The user would type a document on the typewriter. Then,
they would insert a small magnetic card into the large box, and press a
button on the typewriter. The document would then be saved on the card. To
recall a document, the user would insert the card, and press a key on the
typewriter. The typewriter would then type the document out on paper. There
are lots of connectors inside the "large box" labeled things like OPTION and
PERIPHERAL. Using a MagCard or MagCard II would probably be the easiest way
to interface a Selectric to a computer. I have a book that has a picture of
a unit very much like my MagCard II, except that it uses Magnetic Tapes
instead of Cards. It's really fun to watch the MagCard II type out documents
from the cards. It's a lot faster than I thought a Selectric could be.
