CARRY MOST SIGNIFICANT BIT PAC, MODEL CC-034
GENERAL DESCRIPTION
The Carry Most Significant Bit PAC, Model CC -034 (Figure A-20), contains four F-0 1
microcircuit gates and three F-09 microcircuit amplifiers.
These circuits are intercon-
nected to form the most significant bits of the carry net of a digital computer.
