Yes, it is. It's six control chips mounted in one "double-width" 40-pin
package. Socket 1 is the MMU, 2 is the Data and Control package of the
CPU, 3 is the Floating Point. The CIS can go in 4+5 or 5+6, and 7 (or
anything unused by CIS) is "spare". I don't know if there was ever any
other "microms" for an 11/23 or 11/24. Anyone seen any?
