I do have to say the IBM Model 30 (ca. 1969-70) never crashed on me. Not once. <s> I did, however find bug in the basic on the Spectra 70-7 (ca. 1972-73) on which I analyzed data and (in the system editor) wrote my dissertation. Other than that (and Emory had added some stuff into the standard basic that shipped with the machine), never a crash.

Over $7000 in 1984 dollars. I should have hung onto it just so I could donate it to a museum.

>>I bought the OS/2 SDK, if you can believe that. It cost about $3000 and came with about 10 shelf feet of manuals. It was right around the time I realized I was never going to apply myself to it that it became clear Windows had won the OS war.
