I count embedded BASIC as an 'OS' just as I do the ones found in mainstream home machines of the period, although I thought it might be able to use CP/M as an option, as indeed you have pointed out that it could.

CP/M was a good way to get access to a fairly wide 'universal' library of software, perhaps the widest available in the pre-DOS days, although everyone seemed to contrive to use as many different floppy disc formats as possible.

I assume you write your control software in the HP's native BASIC, or was there an assembler available somewhere for this ultra obscure HP CPU?
