Litton - Monroe
OC-8880

Info needed about this obscure CP/M computer!

Monroe - a subsidary of Litton Inc. - used to produce and sell calculators for years from 1912.

Very little is known about this CP/M system. To use the floppies you had to type in OPEN FPY0:

Thanks to Jan Söderberg for the pictures.

The MESS project claims they need its ROM dump.
Pehaps the 2kb image in this link is useful ?

The OC8800 and 8820 were manufactured in Monroe''s plant in Lexington South Carolina. This was the first of two attempts of Monroe to enter the desktop computer business. Operating memory was either 256k or 512K. dual 6" floppies and optional 5 or 10 Megabyte external hard drives. The model shown was intended as a system dedicated to educational use. This incorporated early verisions of software to allow a student to draw and color objects. The acutal commerical version was a single cabinet design with a 80 column dot matrix printer using 4" calculator rolls the display was an orange monochrome 8" monitor.
