The KC85/1 was originally introduced as the HC-9001, "HC" meaning
"Home Computer". But as the industry demand for computers was so
high, they even used these home computers, so the name was changed
to KC85/1, "KC" standing for "Klein Computer", which could be translated
to "Small Computer".
The machine had very limited graphical capabilities with 128 pre-defined
graphic and 96 text symbols in text mode (8x8 pixels size). The
BASIC language needs to be loaded from cassette every time you needed
it (or you could also get it as an optional ROM Module). It has
got an awful keyboard (3 x 10 mm plastic keys), which was quite
a pain to type with for a long time.
There was probably no real reason to prefer it from the other available
models, except its low price, compared to its bigger and more featured
brothers.

Robotron KC85 uses MESS, a free emulator
for a large variety of different systems. Its main purpose
is to be a reference to the inner workings of the emulated
systems. This is done for educational purposes
and to preserve many historical games.
