If my experience on the P800 series is anything to go by, I can offer 
some kind of explanation.

The P800 series came two flavours : development system and turnkey 
system. A development system was harddisc based, for example the 
diskdrives X1215 and X1216, both having a fixed platter and an 
exchangeable cartride. The drives had 2 x  (2.5 or 5 MB).

'The development system could use an operating system like MAS, DOM (a 
very stupid name, as DOM in Dutch means STUPID), DOS or DRTM,

Then you could generate turnkey systems, where the "operating system" 
could be floppy or cassette (ECMA34) based,

Turnkey systems typically controlled process equipment and the like, 
where operator intervention was very limited, normally limited to 
pushing a few buttons on an operator panel, or to load new programs.
