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.

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
