Re: [time-nuts] Obscure HP T/F instruments in ebay.fr
The HP101A and 5275A arrived today. The 101A warmed up in about an hour and the crystal temp settled. It's now reading 98.50 against my 53131A (med. stability option but uncalibrated). I'm not sure what the spec is, or how long ago it was tuned - but even if it was set recently, it's still survived a DHL truck from france with little error.

Before the Keysight split, there was an Agilent museum at HQ in Santa Clara. It was packed full of interesting old HP stuff and even had a part time archivist. I'm now retired and don't know what became of this museum in the split. I feel I got out while the getting was good.

Hi Look at the economics of a museum. Count the heads on the payroll. Count the paying customers you see times the admission fee. At least around here most of them have a budget that looks like: Costs: X Money in from visitors: X/10 Money in from membership fees: X/5 Money from the gift shop: X/5 They either make up the difference: 1) From an endowment. 2) From government subsidies. 3) From other activities (paid research etc). It’s not just electronics that has an issue with this. It’s common in a lot of fields.

Re: [time-nuts] Obscure HP T/F instruments in ebay.fr
This stuff is lovely, but it's enthusiast's equipment, not public or commercial museums. There's a great computer museum in Paderborn, Germany - it's owned by the founder of an ATM company. I love that it has, in Germany, a really good exhibit about Bletchley Park. There's a pinball machine museum in Arizona (I think). It burnt down recently. Again, enthusiasts. Entrance money helps keep it going but it wouldn't exist without the enthusiasts. Here in the UK, there are steam museums. Probably elsewhere too. I grabbed a couple of items from that french auction, fast enough that there was no bidding war. I wish I'd had more - I could easily have outspent myself but I can't move for stuff as it is. I'd be happy to lend them to a testgear museum but I don't know of one, at least not in the UK. The nearest thing I can think of is the Whipple Museum of the History of Science in Cambridge, UK, which has a mixture of medical and scientific gear - not really commercial testgear. For timenuts, there's also the Royal Horological Society's museum which includes a speaking clock, but it's more about timepiece makers than precision.
