This is, so to say, Scrooge McDucks first self-earned dime. I bought
the already completed construction-kit during my studies. What I didn't
consider was the need for a Teletype to operate it. But Teletypes were
in the production use at that time and accordingly expensive. 
To use it anyway, I built a small ROM from germanium diodes and connected
a calculator keyboard and a 7-segment LED display to the parallel ports
of the computer. 
Thus I started programming in octal machine language (no assembler!)
just like others did with the KIM 1 at the same time.

Some technical notes:
The IM 6100 microprocessor used on this board is one of the first 
microprocessors realized with the CMOS technology. The instruction set
is the same than that of the PDP-8.
