Notes The Kaypro line of luggables were strong players in the arena at the end of the CP/M era. They competed well with Osborne, amongst others.
Related Items in Collection Software, manuals, Kaypro Daisy-Wheel printer, box for the system and printer. Other CP/M luggables including the Osborne 1 and Osborne 1a
Related Items Wanted Additional software and additional Kaypro versions

Non Linear Systems began producing portable computers in 1983 starting with the Kaypro II. This machine was designed after the Osborne and had many of the same attributes. Of course, there would have been no reason to create it if there wasn't something better or different. The Kaypro line was built into tough metal cases that were tougher than the Osbornes yet these machines were somewhat lighter.

The Kaypro 2x was one of the last Kaypro models produced. It had 2 floppy drives, a 9 inch monitor (far larger then the Osborne) and a built-in modem (300 baud). It ran CP/M 2.2 just like the Osbornes and could even read and write Osborne disks.

The Kaypro in my collection is a very clean example with all of its documentation and original software. It also came complete with a Kaypro brand letter quality printer which uses daisy wheel technology.

If your Kaypro won't start...

Solder the power connectors/wires!

These are just crimped connections that eventually fail. Soldering usually fixes the dead Kaypro problem.

Best wished for happy computing.

I was friends with and for a time worked for a dealer that was one of the first Kaypro stores. Some of his early machines were labeled 'Kaycomp II'. When a friend of mine bought one, she was given a Kaycomp cover to replace the Kaypro one,so that the store demo could have the newer shell.

The original Kaypros were 2.5MHz not 4. I think that the 4MHz ones were a later motherboard. I think that that's what the '2x' meant. The originals also used full height drives and the whole right side was one big opening for the two drives.

We also did some Kaypro modding. We made a 5Mhz daughter board that plugged into the CPU socket. It doubled the clock speed, but had to add a wait state. This increased the speed about 60%.

We also made a video daughter board that added true descenders and VT-52 character graphics.

I think that I still have wire wrapped prototypes of these lying around the basement somewhere.

Is anyone still interested in purchasing Kaypro items? We are downsizing in retirement and sometime in the Spring of 2008, April or May, we will get our next dumpster. They are on the list to be disposed of ,unless it is worthwhile disposing of them in another acceptable way. Naturally,I will try eBay with a local go between. They served my wife and I very well in the 1980's and early 1990's in our many professional, volunteer and hobbies. I can send you a detailed list with even s/n, model numbers, digital pictures, etc. Briefly: all 6 Kaypro 8's were modified by me from Kaypro 4's using Microcornucopia directions and parts. I kept them running with whatever that was needed including: 2 CRT's + boards 4 main boards 4 power supplies numerous chips including Z80's - A and B, etc. numerous Teac and Tandon drives Technical manuals original software etc. Thanks!

I bought a Kaypro 2X in 1984 packaged with a daisywheel printer. It came bundled with CP/M-80 for the operating system and word processor, spreadsheet, and database applications.

Just to help you out with the summary.

A big improvement that could be made to a 2X was to run ZCPR instead of CP/M. This operating system made full use of the Z80 CPU while CP/M was designed to use an 8080. ZCPR gave you named directories and search paths among many other features. Remember Turbo Pascal? Boreland also created Turbo Modula 2 in a CP/M version but never brought it out in MSDOS. A program called Rembrandt gave the 2X some rough graphics. Smart Key gave the ability to create macros. A communications program called Mite gave terminal emulation capabilities. I used this at work to turn my 2X into a DEC 100 dumb terminal. Dbase, available for a 2X was an excellent database program. I wish I had it on my current computer. Multiplan was a spreadsheet that worked better than Calc Star. Available hardware upgrades were internal 1200 baud modems and internal hard drives (req'd ZCPR?).

(Submitted March 12, 2006 15:46:29 by (a href=mailto:atari7800mod-at-yahoo-dot-com)Mark Graybill(/a))

For manuals on older software, check out and search on the name of the software program in the title field. On dBase I highly recommend the books by Miriam Liskin and Alan Simpson.

Also, Wikipedia has some info here:

On another note:

If you've got a Kaypro you'd like to find a home for I recommend listing your general location. Typically the cost of shipping is more than folks want to pay for a machine that's basically going to be a hobby item these days, so finding a local person who's interested in picking it up from you will often be the best way to pass it on.

If anyone in the east Sacramento/Sierra Foothills area (Roseville, Placerville, Auburn, Grass Valley etc.) has an 8-bit system they want to find a home for, contact me and I'll take it off your hands. Ditto for parts, documentation, 8 inch floppies, etc.

Another unusual Kaypro was the Kaypro 2000 laptop. Mine is fully descked out with a 720k floppy drive, 768k RAM, and all the original software (an impressive bundle in its day). The system has a CGA 4-step mono screen, a detachable keyboard (very rare in any laptop!), and used a very strange battery for those days - a Gates cell. This led to many problems, since people would treat it like a NiCad and run it down to keep the life good. Unfortunately, the Gates cell design is more like the batteries used in emergency lighting - it's designed to be charged at all times, and running it completely down will kill it!

The moderator of this Web site states above that the 2X was one of the last Kaypro model produced. Not so! Kaypro made the inevitable transition into the MS-DOS arena and manufactured computers under the Kaypro brand name through the first three generations of Intel processors. The Kaypro 386 was truly among the last model produced. I was a salesman at a Kaypro dealership in Palatine, IL up until 1988. While other brands were creeping into our product mix, Kaypro was our flagship brand up to that time. I left the Kaypro dealership to launch a desktop publishing company (still florishing 17 years later), where Kaypro 8088 PCs (the Kaypro PC-20 and PC-30) were our platform of choice.
