**A KAYPRO IV IN ACTION SOMEWHERE IN AFRICA**
|
||
|
||
8 Kaypro IV and 2 Kaypro 10 were used by the doctors of the Paris-Dakar race 84's edition. The Kaypro IVs were used to store medical information about the 1000 participants. Power was provided by the Mercedes cars through the 12v cigarette lighters. The Kaypro 10s were kept in the "communication" plane during the day, and were used to centralize all the informations in the evening. At the end of the race, and after 12000 km of tracks, there were all running fine ! One of the Kaypro 10 is said to have been thrown out of the plane, mistaken with a common metallic tool box... And it still worked !

text: We had four Kaypro IVs that we souped up with a speed doubler and four half height drives. Later we put in four double sided 3.5" drives, and still later a hard drive. I did Masters Theses for college students with Perfect Writer, because it was so versatile. Printed them out on a 32 pin dot matrix printer, and later on a postscript laser printer. Took our souped up Kaypro to Bend Oregon to the SOG (SemiOfficial Get Together) a CP/M group. It was a nine day wonder.

text: It had a 4Mhz processor. I''ve owned many computers since that one, but it was my favorite. That and Turbo Pascal 1.5 were a tough pair to beat. It saw me through 4 years of college and then some.

The Kaypro IV (aka IV'83 later) is not to be confused with the [Kaypro 4](/museum/kaypro-4/) (aka 4'84) released one year later. I know, Kaypro model names are REALLY confusing...
|
||
|
||
The Kaypro IV is basically a Kaypro II with DS/DD full-height floppy drives.
|

Wordstar started being included in addition to the Perfect Software suite.
