Not all minis came from the States :-)
That's right. There were one odd swedish mini as well.
Datasaab manufactured a line of minis called D5 in the early seventies. The
D5/10, D5/20 and D5/30. 16 bits.
They were used among others in banks for controlling terminals.
The D5/20 apparently had 64 by 24 bit microcode, used serial arithmetic and
the memory cycle was 1.33 us

There is also the Swedish Ericsson UAC1610 and its successor the APN586,
16-bit computers used in telephone exchanges, management systems for
telephone exchanges and also in railway interlockings. There are about
140 of these interlockings in use in Sweden at the moment; due to
problems with obtaining some components the manufacturer does not
provide spare parts any longer so they are being replaced over a period
of some 20 years or so. I have tried to find documentation on the
Internet but it seems extremely hard to find, if it exists at all
outside of the manufacturer.
