That is probably just the stuff in the drive itself. The real brain, the
2841, was (yes, probably sadly "was") a complicated microcoded box that
latched onto a channel, controlled a number of drives and drums, and
could run diagnostics offline.

Apparently 1130 systems could use 2311s with a control unit located as a
feature of the 1131. Must have been a big feature...or maybe IBM
cheapened the control unit with said one-shots, delay lines, and other
kludges, in order to cram it into the processor.
