An industrial programmer running CP/M-86: Siemens S5 PG 685

EkriirkE · May 26, 2020

I didn't see any rule restricting to Z80 but this little guy runs an Intel 8088 @ 6MHz (I think) with 512KB RAM and a 20MB HDD on a backplane system. I could not find any Siemens software on it other than the licensed CP/M-86, and S5 PLC design files. I suspect maybe the designer/programmer software was contained on a diskette. However there were games "hidden" in another userspace... I doubt DOS would run on it.

Fun fact: the HDD in this machine is a Tandon TM262, the company Western Digital bought to start their HDD business (previously they only made the controller cards) and this model they rebadged as WD262

That's not unusual--22Disk has a definition for the Siemens boxes--and I have samples in my archives.

Several Japanese PLCs (e.g. Mitsubishi) ran CP/M-86 for a time, before moving over to (Japanese) MS-DOS. I believe that Electroglas also used it. Tokyo Electron Microscopes used it.

There are other examples.

Look if you have the OUA11 or OUA12 model (check the model no. on the back).
OUA11 is text mode only and has a 8088/V20
OUA12 has a graphics card and a 80286

There's a DOS version for those not-so-compatibles, and a DR GEM version for OUA12.

The CPU card had an 8088 as mentioned
