In my workplace they used Philips ( one l please , not
two...) P856 and
P857
16 bit minicomputers to test watch IC's. All these minis were dumped,
I rescued just one , plus some spare boards to keep it running.
No software could be found to for them.
I got some 8" floppies with my P851 and P854 machines, at least one of
which is claimed to be an OS boot disk. I've not done anything with them
yet, but they are safe.
A fried wrote a monitor program from the P850, which loads from paper
tape. I should still have the source and binary around. I would have to
ask him what the copyright situation is, but I can't believe he would
object to another enthusiast running it.
