KIM-1 Board Computer
The KIM-1 was the first computer that was made using Peddles
6502 processor at MOS technologies. The computer was a very simple
one with 6 LED digits, a hexadecimal keypad, 1kb of ram and a simple
but good built in monitor. In addition there was a number of connectors
that allowed you to add all sorts of pheripals like a serial terminal
or a cassette recorder. Shortly after it was created, Commodore came
along and bought MOS simply because they needed to manufacture their
own chips for their calculator business! What a lucky coincidence that
the skeleton of a whole computer was taking its first steps.
The computer was meant for universitys and hobby enthusiasts who
wanted to learn about modern computing at an affordable price. The
user had to type the program in by entering assembly op-codes and
there were a set of buttons to move the program counter and run
programs. There was even a button to step through your code for
debugging purposes. It brilliantly simple, but alas difficult to
program. But remember these were days where people knew the 6502
opcodes and their hex values by heart! :)
The first boards that were released by MOS were green, and
the Commodore owned versions used a White board and has the
Commodore logo on it.
