Appendix: The Kaypros

Many were the virtues of the Osborne 1, but its tiny screen caused no end of grief. So, a company in California introduced the Kaypro, a comparable product with a 9-inch screen. By late 1984 the Kaypro had usurped Osborne's position as the standard Z-80 CP/M luggable. Bundled with plenty of industry-standard CP/M productivity software, the Kaypros were an outstanding value. Later on, advanced versions were developed. Model 10 had a 10Mb hard disk. Model 16 abandoned CP/M for DOS.
