Paul Allen’s Estate Auction Includes Vintage Apple-1, CP/M and DOS-Powered Computers

Long-time Slashdot reader theodp writes: Christie’s this week announced the items that will be auctioned in three sales from the Paul G. Allen Collection, including historic computers and artifacts from the late Microsoft co-founder’s former Living Computers Museum + Labs in Seattle.

They include an Apple-1 from the desk of late Apple co-founder Steve Jobs, estimated at $500,000 to $800,000, to be auctioned as part of a live sale on Sept. 10 at Christie’s Rockefeller Center in New York.

Among the lot of “Firsts” from the Paul Allen Collection is a circa-1984 PC’s Limited Personal Computer (est. $600-$800), which comes with a manual for the Microsoft-developed IBM DOS. Also being offered is a circa-1975 IMSAI 8080 microcomputer (est. $2,000-$3,000). Both computers ran operating systems that can be traced back to the efforts of Digital Research founder Gary Kildall. Kildall’s CP/M was adapted for IMSAI in 1975 and inspired the “CP/M work-alike” Quick And Dirty Operating System (QDOS) that Microsoft purchased in 1981, ported to the new IBM PC as MS-DOS, and licensed to IBM, who in turn offered it as PC-DOS…

Interestingly, not present in the any of the three Christie’s Paul G. Allen Collection auctions is Allen’s rare unedited copy of Kildall’s Computer Connections: People, Places, and Events in the Evolution of the Personal Computer Industry (edited version available at CHM), one of only 20 copies that were originally distributed to family and friends shortly before Kildall’s death in 1994. (In the unpublished memoir, Kildall’s Seattle Times obit reported, Kildall called DOS “plain and simple theft” of CP/M). Documents released in response to a 2018 Washington Public Records Act request revealed that one of those copies found its way into the hands of Allen in 2017, gifted by University of Washington CS professor Ed Lazowska, who led fundraising campaigns for UW’s Paul G. Allen Center for Computer Science & Engineering.
