of the more inexpensive early kit computers was the Commodore
KIM. Based on the 8-bit MOS 6502 CPU (which sold for $25,
compared to $150 for the Intel 8080), the KIM came with built-in
hex display and hexadecimal keyboard. It had a clock speed
of about 1.8 mhz and could address up to 2 kilobytes of RAM.
This KIM-I "homebrew" was heavily modified, and
was hooked up to a black-and-white TV as a monitor, as well
as a Teletype and electrostatic printer.
