In the early 90s, on two separate occasions, I was offered "3 Altos" for just a few dollars (one batch was from Stanford that had been using them for printer servers, and I don't remember where the second batch came from).

Over the years I wound up donating them to various places (the Computer History Museum, the Kyoto Prize museum, the Boston Science Museum, etc.). We kept one at Viewpoints as a mascot, and my last one I gave to Sam Altman because he wanted to do a restoration. That one turned out to be a late hybrid that Ken Shirriff and company are having fun puzzling out.

The "random mouse on ebay" was at my suggestion, because the Alto I donated to Sam didn't have a mouse.

Most of the original runs of Alto IIs (at least 1500 of them were built) cost in 70s dollars about $22.5K apiece. Inflation (according to the web) since then has been about a factor of 5, so each Alto would have been about $112.5K (and I'd love to have a $112.5K personal computer today -- that would really be "computing in the future" as we did at Parc).

Actually it doesn't seem that weird to me. I don't recall anyone who bought a system from Xerox (as I recall they were in house development only and cost about $75,000 each to produce). But I do remember when they were being scrapped and the word went out that some ex-Xerox employees were rescuing them and looking for others to take some. I was sorely tempted to take a Dandelion machine (this was the mid-range D-machine that I was most familiar with). I could easily imagine that Alan said "I'll take one" and whomever was organizing the rescue made sure all of the "parts" were included when it was long past the time when you could easily boot one up and see if it worked or not.
