In 1979, Two of my college friends and I started a small business selling Morrow Design computers and writing software while attending Northwest Nazarene College, Nampa, ID.

We sold quite a few MD1, MD2, and MD3s. Sold one Decision One to a client that needed a multi-user system.

Somewhere I have all the sales material for the computers (three ring binder). If I can find it, I will scan them and send them to the site.

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

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.

To Greg H,

It''s a standard 25 pin RS-232 connector. If you get a 9 pin to 25 pin cable, you should be able to make a PC act as a terminal (with appropriate software).

I have one of these - and all the software, it was my first real computer in college. The Liberty terminal is long gone, but I have the rest of it. Was going to see if the floppies had anything on them and try to at least boot the thing. Need pinout for the terminal port. I''ll just have to meter it out.

My first PC was a Morrow MD-3. Many nights spent playing adventure, zork and racking up phone bills on CompuServe.

I used Morrow MD3''s in my Computer Science class in high school. This was in 1991, believe it or not, in Anacortes, WA. They were pretty rickety little boxes... I''ve owned a couple in the past and it gets me when people complain about DOS and how antiquated it is. They blab about their prowess with the command line and know nothing about good old CP/M. I also had a couple Morrow MD3/P''s, the portable $luggable$ version.

My first real computer (I had a RadioShack Pocket Computer first, but that doesn''t count), was the Morrow MD3. I still have it, but had to get rid of the Liberty terminal.

I did my senior project on that computer - a terminal system that I could use to log in to the school''s Univac and also do file transfer, etc. between the systems.

in 1984 I purchased two MD 2's and the dealer, the AB Dick franchise in Bakersfield, CA, asked me to start up a computer users group. Later I bought an additional used MD 2. All three of these MD 2's had two DSDD floppies and Personal Pearl, but not Quest. The WordStar package included SpellStar and CalcStar. I loved that system, even the 9600 baud serial terminal connection. I tried to stay with C/PM as long as I could.

My first real computer was a Morrow Design Micro Decision II, Z-80a processor, 64 KB memory and two 186KB 5-1/4 inch floppies. It came with a Freedom 50 terminal and a number of software titles, including Wordstar. I eventually added a Radio Shack Model 100 laptop that could interface with the terminal connection on the MDII. Great fun, and it worked, but you had to be a serious hacker/geek to get things to work correctly.

I still own my first computer: the Morrow Design Micro Decision with 2 Floppy Disk Drives. Now more then 20 years later I am still in the Computer Business and that is also because I loved by 1. Computer. Thanks to Morrow!

Morrow was very active in the 80's designing S-100 and SS-50 addon boards. In addition to the memory board, he designed serial and parallel I/O boards, Eprom boards and burners, and disk and tape drive boards. I owned one of his 32K ram cards, fully populated (for a system total of 40K !), I spent over 750.00 for 32K. :-)
I had a no-name mainframe, 22 slot motherboard, S-100 box back then...
