Reddit user c-wizz, who discovered a large number of "ancient computers" in the basement of his grandparents' house, posted this image. At the risk of sounding like a millennial (I don't identify as a millennial), these PCs are truly amazing when it comes to computer history. Sure, they're not as old as the oldest computer ever discovered (opens in new tab), but there's some real history here.

The computer posted by c-wizz (opens in new tab) includes the LGP-30 (opens in new tab), which was introduced in 1956. It had an MSRP of $47,000, equivalent to about $458,522 (about $390,970) in today's monetary value. This model is a Eurocomp, one of only 45 built by Schoppe & Faeser, according to the Time-Line Computer Archive (opens in new tab).

The PDP 8 was the first mass-produced minicomputer, and according to the book DEC Is Dead, Long Live DEC: The Lasting Legacy of the Digital Equipment Corporation, the first computer to sell for under $20,000. It was also the first computer to sell for less than $20,000. The PDP 8/e, which c-wizz is currently staring at, was introduced in 1970 and was the first to cost less than $6,500 (opens in new tab).

c-wizz plans to contact the Time-Line Computer Archive for more information. 'The only thing I know is that my grandfather used it in the 60's for civil engineering calculations,' they write in their comments. 'My grandfather was one of the few people who personally owned such a computer.'

As subsequent comments point out, owning a computer in the 60s was indeed rare, and perhaps c-wizz's grandfather was in the very privileged position of 0.01% of the workforce. Whether that indicates that his grandfather was anything more than a mere civil engineer, however, remains to be determined.

Another comment contributor reveals that he is another owner of a rare LGP 30 that is currently undergoing "long-term restoration." These are delicate machines, they noted, and if by any chance the internal drum were to rotate in an oxidized state, the c-wizz would be "SOL."

They are planning to get the machine up and running again, but from the above it doesn't sound like an easy task. c-wizz also says, "I found a museum in Germany (where I'm from) that apparently has a working LGP-30. I will try to contact them.
