The tech industry you are referring to(SiemensNixdorf/Commodore) was mostly consumer hardware and has along with the likes of Nokia, Motorola and Sony Ericsson long moved to Asia or disappeared all together as margins are thin in that business and cost of labor is too high in Germany.
Consumer focused software is where the big money is now an that is unfortunately a huge vacuum in the German tech sector.

Both Siemens and Nixdorf build mainframes. Later Siemens had it's own version of DOS. Most Commodore PCs were used in office environments. I am not referring to 8bit machines nor Amigas.
