The Monroe OC-8820 was an all-in one Z80 based system featuring 128 to 256 KB of RAM, a monochrome CRT and a dual 5.25" 300 KB floppy disk drive.
It used its own multitask operating system, but a CP/M OS could be acquired separately along with a specific Monroe BASIC interpreter, Dbase II, Wordstar and a spreadsheet (probably CalcStar). Even under CP/M, You could run the a Spreadsheet report and still run Wordstar.
A 10 MB hard-disk drive unit was also available.
The Monroe computer family also had a color graphics model, but we have no information about it.
