It's an analog computer; NO bits! Or infinite bits, if you prefer :-)
I used one in college. They are really neat machines. Basically, a bunch
of analog opamps, with the inputs and outputs readily accessible on the
front panel. Almost any imaginable differential equation can be solved
on them, but it would be useless for adding 2+2.
