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.
