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.
