The history of Philips' computer divisions through the years is interesting and rather obscure. After building mainframes in the 60ies (P1000) they went on to develop minis such as the P800 and P4000 in the 70ies/80ies. As far as I know this was both developed and marketed mainly in Europe, the P800 for industrial control and P4000 as an office computer. This was very proprietary stuff (both hardware and software) and details are sadly hard to find online these days. Later, Philips abandoned their home-grown efforts and went on to produce PC clones, although I believe there was also something Unix-based (P9000?).
