K20

"The K-20 computer from High Tech Research looks like an ordinary CP/M Kaypro 10 - it even has Kaypro written on the side in familiar gray letters. But don't be fooled. The K-20 is about as much like a Kaypro 10 as a Saturday night street racer is like the family sedan.

... To make the K-20, High Tech REsearch buys '84 series Kaypro 10s directly from Kaypro, complete with clock, internal modem, and software bundle. High Tech then modifies the basic Kaypro 10 as follows:

In place of the Kaypro 10's ten megabyte hard disk, the K-20 has a 20-megabyte Seagate 225 hard disk ... And in place of the usual 390K double-sided 48-track-per-inch floppy disk drive, the K-20 has a double-sided 96-track-per-inch floppy drive storing 782K.

In place of the normal Kaypro ROM chip, the K-20 has the latest Advent TurboROM. ...

Finally, the K-20 has the latest version of Handyman(1.3), a SideKick-like popup desk accessory for CP/M Kaypros." (Profiles, V5, N1, Aug 1987)
