Their websites are https://www.sbhp.nl/ and https://www.philips-museum.com/. Both are in Eindhoven, as is much of the interesting bits of Philips itself. The former appears to be volunteer collectors of mainly analogue-era Philips gear and I can almost smell the chain-smoked roll-ups just from the photos, whereas the latter looks rather more corporate. (I am occasionally contacted by Philips' recruiters trying to lure me to work at some nasty industrial park near Eindhoven airport. There is usually tumbleweed after I point out the seven hour commute and ask if they've considered remote-working.) I only note this because I have Weekend Vrij and a Museumkaart, and my random spin for where to visit this weekend landed on Eindhoven and thence to the Philips Museum, which reminded me of this thread. Unfortunatly, SBHP is closed at weekends (and doesn't accept Museumkaart, but I could have probably scraped together the €4 entry fee) which is a shame as it looks by far the more interesting of the two. If I spot a P2000C and remember, I'll try and get a photo although I doubt they'll let me dig it out of the cabinet and go over it with my micrometer... It may also be worth reaching out to the HomeComputerMuseum (sic) in Helmond (https://www.homecomputermuseum.nl/) who are quite friendly and have a well-curated collection, including quite a lot of Philips gear. It's not directly relevant to this query, but they have a very impressive collection of CD-i machines, hardware prototypes, and media. They have a P2000C, which is on display for the public to use, and a suitable donation would probably get all the photos and measurements you want: https://www.homecomputermuseum.nl/en/collectie/philips/philips-p2000c/ As a last resort, there's the Bonami Games and Computers Museum in Zwolle (https://computermuseum.nl/) although it's basically just a huge barn with a load of random stuff piled in it and poor labelling, so I'd try them last: I took some lovely atmospheric pictures of 60s and 70s Big Iron when I visited, but have no idea what half of it is. I suspect they don't know either.

The website has a "collection" tab that doesn't say anything about a collection. The "eyecatchers" tab speaks of an exhibit of Philips advertising posters. Ok, nice, but what does that have to do with the technology and products and enormous R&D contribution of the company? The former at least shows something about the collection, a set of nice photos of stuff. That and a hint that there is more -- but no description of what that might be. I keep wondering if anything whatsoever about the PR8000 has been preserved anywhere. I have a marketing brochure that I scanned and sent to Bitsavers, plus some notes about the parts of the instruction set that show up in a program of mine. But I've never seen anything else, even finding any mention of the machine is nearly impossible. I still regret I didn't save the Stirling cryogenic machine brochures I had as a teenager -- neat machines Philips built for easily and cheaply making lab quantities of liquid nitrogen and even liquid helium. Some were backpack size, apparently for airborne applications. I also had a brochure of their neutron generator tube, which is a pretty wild device. paul

So to speak! I didn't see their liquid helium machine. I remember one installed at the TU Eindhoven physics department; it consisted of a pair of two-stage Stirling machines (which by themselves will liquify hydrogen or neon, i.e., they go down to about 20 K) plus a bunch of auxiliary equipment. The whole setup took maybe a 15 foot square room. The website doesn't show any of the compact machines I remember seeing described. A bunch of those had 400 Hz power, indicating they were meant for airborne use. One was a little lab bench machine, a box perhaps the size of an old style desktop PC, lying flat, with a "cold finger" sticking out of the box. paul
