I lived in Munich, Germany for a year and a half back in 1983 while I was
working for Applied Microsystems. I developed a couple of the EM series
emulators and ran into a number of remarked Intel systems that said Siemens
on the outside.
I've never heard of a Siemans system. The white
MDSs that I've seen all
have the standard Intel markings and labels. (I've got one sitting about 3
feet from me as I type.)
