Is it possible to get an original DEC pdp-7, if so how much would it be? I've looked around the internet, but I'm not finding anything.

    While this is clearly off topic for RC.SE (where to buy X), it's also a funny question. I like it. Serious, Any surviving is either in a museum (or company/institute collection), or very deep stored in some basement. Not really anything advertized in public. – Raffzahn Jan 10 '19 at 17:33
  • Yeah, sorry, it was right after I posted this that I found a list of all surviving pdp7s there are 5. Oops. – Shadow Jan 10 '19 at 17:40
  • @Shadow This is definitely off-topic, but which list says 5? The one from the answer says 4, and it'd be interesting to see the difference between the lists. – wizzwizz4 Jan 10 '19 at 21:54
  • Oh, oops I meant 4. Missed typed on phone. – Shadow Jan 10 '19 at 21:55
  • Somewhat apropos: In the early 2000s I came across a small DEC system (single rack PDP-11 plus an ASR 33, IIRC) thrown out with a bunch of regular trash. This was on a commercial street in a residential area. My guess it came out of a medical office. Still kicking myself for not snagging it for my collection. So keep your eyes out, you never know what you might find! – Alex Hajnal Jan 11 '19 at 9:06

PDP-8 and PDP-11 machines seem to be much more available. The Living Computers museum in Seattle has a PDP-7, which may be running: it would be worth asking them if you could have a login for it.

To buy one, start haunting eBay. Price would be unpredictable, and probably quite high for something in running order.

  • I did not know that place existed, and I live in the area, will definitely be going there soon. – Shadow Jan 10 '19 at 17:56

    The LCM is definitely worth a visit. Though it's pretty weird to see "things I have worked on" in a museum. – another-dave Jan 11 '19 at 3:00

In short: no.

A well-researched list of PDP-7s sold and their fates is available here from soemtron.org. There were approximately 50 PDP-7s manufactured, of which only 4 are still known to exist. They're all in museums.
