    It's like RAIDs - drives still fail, but data is saved.
    Only in certain modes, in other modes they are even more unreliable.

      I sometimes wonder if Lemmy is indeed the reincarnation of our beloved Wolfgang.

        Didn't then, won't now.

        (not with 741s anyway - maybe the newer CMOS Op Amps would hold up)

          I wonder if I can find it.

          I had to do analogue computer programming for a degree level module once... tricky stuff.
          I worked on some multi-DSP nonsense once that was meant to be a replacement for an analog computer in some aeroplane simulator, but apparently the aeroplane it went in was real and simulated other aeroplanes or something. Never did quite work out what was going off and the processors then just were not fast enough. Good idea, just too far ahead at the time.

            If you fancy wandering to Doncaster there are possibly several hundred back copies of PE, PW, ETI, Elektor, etc. old Maplin and RS catalogues etc., all going mouldy in a cellar if you want them. Strong back and a large van required if you want them.

            Hmm, best let me check on just how mouldy they are as I haven't been down the cellar of that house for several years.

            Hmm, wonder if that's where I've left the other VOX AC120.

            Hmm.
