George Morrow, the Morrow Designs President, was one of the first engineers to design and market a memory board for the Altair computer. His company was first called "Morrow's Microstuff" and the cards were sold by mail order. Some time later, Morrow Designs began to design hard disks and computers.
With this computer, G. Morrow tried to build a single-board Z-80 CP/M machine that looks like an IBM PC but is one-third as expensive as it, and half the price of a comparable Apple system (Apple III).
The basic version included a serial video terminal and a 200 KB 5.25 floppy disk drive. However, the mainframe could be sold alone with one or two floppy disk drives. The Micro Decision also came with 5 MB, 10 MB or 40 MB Winchester hard drive installed. The MicroDecision line didn't have proper monitors or keyboards. The console shown here is actually a VT52-compatible terminal.
Here are the diffent models marketed and their US price in 1983 :
Model MD1 : one SSSD disk drive (200 KB) = $1590 Model MD2 : two SSSD disk drives (400 KB total) + Personal PEARL DBMS = $1950 Model MD3 : two DSDD disk drives (768 KB total) + Personal PEARL DBMS + QUEST Bookkeeper = $2490
The Morrow MD-1 used the Pilot programming language for a Menu-Driven shell to make the computer more user friendly. Some of the later ones manufacturered also used CP/M 3.0.
Like many CP/M computer manufacturers, Morrow Designs offered a complete software package with its system, including:
- CP/M 2.2 operating system
- WordStar word processing from Micropro
- Microsoft BASIC-80 programming language
- NorthStar compatible BAZIC language from Micro Mike's Inc.
- A spelling checker
- An electronic spreadsheet.

I bought a Morrow MDII in 1982, because I needed a computer to manage a multi-defendant t lawsuit I wanted to file. (I am a lawyer.) I couldn''t handle it without a computer which I understood would do the job. It did I could run a law office with that computer. It was a revelation to me and a revolution.
It finally failed Disk drives I failed as I remember. Still have it. Anyone have any ideas onail how how I could get it fixed. E-mail me at email@example.com

They sold these Morrow computers ar Von''s Computer Store In West Lafayette Indiana when I was in college in 1982. I remember thinking that the Morrow wa the only system that I would consider buying at that time. The system looked good, felt good and, above all, just worked. It was relatively inexpensive and came with useful software.
