Hi,

My rarest computer is a Nokia Mikko-1. Made by Nokia of Finland in the
second half of the seventies. (The g.o.days N. still was a decent company).

This computer was build as a 4 bit slice on one 4" x 9" pcb, so there were
8, 12, 16 and even 20 bit versions of it. The instructionset was
microprogrammed on another control-pcb, and since different departments at
Nokia had different opinions on what was a suitable instructionset, there
were at least 4 different instructionsets simultanousley in continuous
devellopment. It was programmed in assembler only, whith some
cross-compiler running on a PDP8-E with a RF32 attached. It was using Intel
1103 RAM and 1602 ROM or 1702 Eprom. Several thousands were manufactured
and used in many different industrial aplications, and as embedded systems
in the NOP30 time-shareing terminal or LP4900 multi-channel analyser.

I have no idea how many there are still alive, I have 2 systems, and will
put some photo's on-line sometime next week. Anyone else has such a beast
or its successor Mikko-2? (mainley used in banking applications).
