1980-01-01 is the (PC|MS)-DOS epoch. Early PCs did not have a battery backed clock, and so every boot would require manually setting the clock -- and many people did not bother to do so, hence timestamps of that date are not to be trusted. That would explain those, yes.
I've still got the 8" floppy disks from the TI system that predated my getting my first PC ... only problem is the lack of hardware that would actually read them to see what the dates were. Certainly around 1980 as that was when I got my masters in computer systems. And I was working on TV systems for a few years before that with EMI Electronics. -- Lester Caine - G8HFL ----------------------------- Contact - https://lsces.co.uk/wiki/?page=contact L.S.Caine Electronic Services - https://lsces.co.uk EnquirySolve - https://enquirysolve.com/ Model Engineers Digital Workshop - https://medw.co.uk Rainbow Digital Media - https://rainbowdigitalmedia.co.uk
