Siemens
SME

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.

When I was a child, coleague of mine got from somewhere simillar unit. 8080 based, SME compatible Siemens computer. It was very simillar to the one, presented on this site, but it was not identical. Some time ago I found on some Danish or Switzerland old computers museum (I don$t remember site) video, where guy is booting CP/M on machine identical to the one I saw in my childhood and as far as I know compatibile with SME.

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.
