History
Computers such as the Kaypro II were widely referred to as "appliance" or "turnkey" machines; they offered little in the way of expandability or features that would interest hackers or electronics hobbyists and were mainly characterized by their affordable price and a collection of bundled software. While it was easy to obtain and use new software with the Kaypro II—there were thousands of application programs available for CP/M, and every Kaypro 8-bit computer had a full 64 KB of RAM, enough to run virtually any CP/M program—the hardware expandability of this computer was nearly nonexistent. The Kaypro II had no expansion slots or system bus connector, no spare ROM socket, no peripheral bus, only two I/O ports, and an ASCII text-only green-on-black video display, of 80 x 24 characters, that could only be shown on the internal 9" CRT monitor (despite the video being scanned at NTSC TV-compatible rates).
