Kaypro 1

The Kaypro 1 was the last CP/M model Kaypro introduced. In most ways, it was simply a Kaypro 2X with a smaller software package. It is distinctive from earlier Kaypro models because of its vertically oriented disk drives. (1986)

Narrative »

• I received a phone call where I work asking if we buy old computers. Ever the opportunist, I asked what it was. Met the gentleman at his house, paid him for the unit and here we are.
• This machine, as received, was a weird hybrid.
  •  It is supposed to have: Kaypro 1 ROM, Kaypro 1 Disks, and Double-Side floppy drives.
  • Instead it had: Kaypro 2/84 ROM, Kaypro II disks and single-side floppy drives.
• The machine has been restored to factory configuration by installation of a freshly burned ROM and double-side floppy drives.
