In the 1970s Philips launched their P800 line of microcomputers. The P800 is a 16-bit architecture with 16 registers of which 14 can be used for general purpose. The processor could address 32 kWord memory (with tye MMU option). The line of computers was developed by Philips-CTI in Fontenay Aux Roses near Paris, France
From the System Description Manual: The P855M and P860M are general- purpose digital mini-computers ideally suited for industrial and scientific applications, such as process control, test and measurement, data acquisition, numerical control and_ scientific problem- solving.
Elsewhere is more extensive description of the P8xx family, but the exiting part is that eventually in the early 1980s the whole processor fitted in a single 40-pins integrated circuit, the SPC16/10. Some of the later members of the family were created around this part or its successor SPC16/20. The SPC16/11 and SPC16/12 are support chips.
In this family tree document is an overview of the models of the P800 line. The P851 was widely used to control agricultural greenhouses automation.

In 2024 Jos Dreesen announced he was creating a single board computer around the SPC16/10. Eventually a small batch of I.C.'s was purchased and several boards were build. This board is one of this batch.
