Philips machines (and AMT DAPs)

I wonder if anyone on this list knows anything about the minicomputers that Philips were making in the 1970's? They seem to be somewhat uncommon, even though a lot of different models seem to have been produced. Two that I know about are the P850 (a 16 bit machine, with a maximum of 2K words of Core and 9 I/O slots, all built from discrete TTL), and the P851 (a later machine using LSI chips (SPALU was the ALU/register slice, PLANET was the control sequencer, taking a maximum of 32K words of MOS RAM). The P852, P853, P854, P855 (== P850 with more instructions), P856, P857 and P860 are all mentioned in passing in the manuals, but I have no real details The other thing I am trying to find information on is the AMT DAP (Distributed Array Processor), which seems to have been a square array of custom single-bit processors. It's a little too recent for this list (it seems to have come out about 9 years ago), but as it's not a PC, I doubt anyone will mind discussing it here. -tony
