The Monroe 1880 was the top of the line of Monroe's 1800-series calculators.
See the exhibit on the Monroe 1860
for information on a very similar machine. A copy of the
Monroe 1880 Programming Reference Manual
is available through the Old Calculator Museum's manual archive.
Monroe's 1800-series calculators were manufactured exclusively for Monroe
by Computer Design Corporation (Compucorp).
