Then again, the 8870 mentioned in Albetos original
question is
a small multi user system for office tasks.
Is there a document that describes the various Siemens Siemens/Nixdorf
computer families, with release dates?
The late IBM-compatibles have some documentation, but there isn't anything I
see on the web that gives the progression from the 4004 forwards, or the
Siemens 16-bit process control systems from the 70s.

It would be a lot easier to identify the pack if there was a picture, or at
least a description of size, #platters, etc.
