I think Holm nailed that one. The logo is probably just a coincidence, as
it's pretty safe to say this board didn't originate in the 'Bad Old Days'
of the DDR.. ;-)
Seems like MCT in Shoreview, MN is our best working hypothesis. Would be
nice to come across an advert or other piece of corporate ephemera from the
early 1980s, to see what logo they used.

http://www.mct.net/ - Does that logo look familiar? Founded in the
80s,
controller boards, interface modules, single-board computers.. but yes,
they are in Germany. I did try contacting them, but never heard back.
They claim "Embedded Control know-how since 1984." but you have 1980
and 1981 date code parts on your board. It's possible they made the
board before they knew how however. That is not unheard of. :-)

I'm sure, that's not the company that build that S100 Board. Ranzin, where
mct.net is located, is former eastern germany (GDR) area (as my home is
too)
and S100 Buisses where simply not used before here before 1989.
Ther embedded control experience in this timeframe will be mostly an Z80
compatibles (later Z8 too) an K1520 Bus systems. The AY3-1015 however was
available as TESLA MHB1012 or so, not as GI part.
