Nokia MikroMikko 1 M6

MikroMikko was Nokia Data's attempt to enter the business computer market. The computer has 64 Kb memory and CP/M operating system. There are several models of MikroMikko 1, and this M6 model has two 5,25" 640Kb disc drives and high resolution graphics capable of 800x327. The keyboard weights about 2 kilograms. It was a very robust built system that was very suitable for hard environments such as schools. The machine has a linear power transformer and no fan. Cooling is done by a giant heat sink on the back side of the machine.
Ergonomics has always played a great part in the MikroMikko series and this model has a keyboard with a built-in wrist support and a very slow screen that is very comfortable even though it has a 50Hz refresh rate.
Nokia later bought Ericsson's computer division. Later ICL bought the Nokia Data from Nokia that concentrated on its key competence. This machine is peculiar in that sense that it has the old Nokia logo that reminds that the company was originally making car tires besides rubber boots and cables. Computer manufacturing has ceased in those plants that made this machine. MikroMikko got several follow-ups: MikroMikko 2 had a very nice display with white background and 72Hz refresh rate, it was also the only real computer that was made with Intel 86186(!). While MM2 was partly MS-DOS compatible MikroMikko3 was an ergonomic beauty that was fully pc-compatible.
