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.
