In the late 70s Siemens licencied the Intel 8080 processor and became a 8080 chip second source European manufacturer.

After having translated the 8080 user's manual to German, they marketed the SME development system ( Siemens Microcomputer Entwicklungssystem) which was the same system as the Intel Intellec Series 2 MDS (Microcomputer Development System). The system had a 8080 processor in its first version, later an Intel P8080A-2 (an increased-speed 8080), then finally a 4 MHz. 8085.

For the major part, the SME was made by Intel in USA. The only difference between Intel and Siemens systems was the cabinet colour: grey for Siemens's, blue for Intel's.
The SME system was very popular with german 8080 /8085 hardware and firmware developers.

Thanks to Gottfried Silberhorn from Germany for information and pictures.

We need more info about this computer ! If you designed, used, or have more info about this system, please send us pictures or anything you might find useful.
Please consider donating your old computer / videogame system to or one of our partners from anywhere in the world (Europe, America, Asia, etc.).


I used this system about 15 Year's ago for Software/Hardware develpment in Siemens-Albis AG, Zurich, Switzerland.

I remeber that there were up to 10 drives, :F0: to :F9:, :F0: used to be the boot drive!

each Filename had up to 6 characters, the Extension had up to 3 characters.
