Monroe 1800-Series Advanced Programming Reference Manual
Sincere thanks to John Engels for donation of this document to the museum
Front cover of Monroe 1800-Series Advanced Programming Reference Manual
This document outlines special "machine-level" advanced programming methods
for the Monroe 1800-Series electronic calculators. These calculators
utilized an advanced, computer-like microcoded chipset that, along with normal
"learn-mode" programming function, allowed access to some of the lower-level
microcode routines by the programmer. This could allow advanced operations
such as binary logic operations, direct access to memory and storage registers, and advanced control of peripheral devices.
See the exhibit on the Monroe 1860
for an example of one of the Monroe 1800-Series calculators.
Monroe's 1800-series calculators
are OEM versions of calculators made by Computer Design Corporation (Compucorp).
