K > KAYPRO > Kaypro 2x   


Kaypro
Kaypro 2x

The Kaypro 2x was one of the last models Kaypro produced. Size and appearence were the same as the first Kaypro II, but Internal hardware was inspired by the Kaypro 10.

It came with a 4 MHz Z80A processor, dual slimline 400 KB floppy drives, a built-in 300 baud modem, two serial ports and a full set of Micropro software (WordStar, CalcStar, DataStar)

It is said that Arthur C. Clarke worked in the movie version of "2010: Odyssey Two", a sequel of "2001", using a Kaypro 2x and its built-in modem for transfering texts from Sri Lanka, where he lived, to Los Angeles.

Roy Miller specifies:
I own two. One looks like the machine you have (colors of the original 2), and has the same equipment. The other doesn't have a modem, and came in the same color scheme as the 4, 10, and 16.
The one in the older color scheme has a sticker with an "X" on it pasted just after the "2" on the back. The dark grey one doesn't have that. It seems clear that they used the older 2 cases as well as newer cases.

More info about the internal modem by David C. Oshel:
The internal modem didn't work with the software Kaypro provided, so you had to use a Hayes Smartmodem attached to a serial i/o port. The internal modem chip had a defect: One of its pinouts went low when the specs said it went high.
We put an oscilloscope on the pup and saw this for ourselves on the Beacon Microcenter (Ames, Iowa) workbench in 1983. I was able to write a driver that made it work, but nobody cared.

I just acquired a Kaypro 2X at the local used bookstore for $50. Although the keyboard was demonstrated to me in the store, I bought it without a keyboard cable and was wondering if anybody has one. Please email me at glendon144@gmail.com if you have one, thanks. I''ve tried making one from a handset cord without succiness. The machine does boot into CP/M.

This picture looks like what I always referred to as a "New 2" - a machine that looked like the old 2, only with half-height DSDD drives.

There''s another 2X, only this one is gray and has both the modem and real-time clock. The one I currently have still keeps time, although the year went funny after 1999.

I bought a 2X to modify, as I wasn''t sastisfied with the 10$ threw in a Seagate ST-225 (whose odd ''ratcheting'' noise as it started I still miss to this day!), some ''pigghybacked'' ttl chips on the decoder circuit to double the floppy storage, a pluPerfect Systems BIOS, and a MEG of ramdisk - don''t even want to think about what that cost$)
