    You can get some crazy sounds out of these pickup coils if you pair them with a portable MiniDisc recorder. Fun stuff.

    I'm glad I'm not the only one who used this thing for anything but the telephone!

      You are not the only one, I used it on the RCD (Circuit Breaker) with the washing machine running the whole cycle. It can pick up sounds from power lines and other electrical sounds in the streets of a town or city but the latter 2 may be awkward for those who do not wear a listening device to listen for them in 1st place.

    I was today years old when I learned that hard disks loaded their firmware "live" instead of it coming from a ROM...

      Yup! This is why you can *sometimes* revive a dead modern disk by swapping the PCB.

      Yep - as hard drives got more complex the amount of code got to be too large to store in FLASH or a ROM chip. It turned out to be more cost effective to have a minimal boot loader to get the drive started, and then to read the full code set, performance tables, etc. from a reserved area on the drive. Hence the two stage boot process.

    Is that IBM one of the disks with glass platters?

      It is possible because some of the Deskstar line used those, but I don't have a cross reference that will tell me. Normally you can't tell unless the platter is shattered or is damaged because the glass is coated just like aluminum platters are.
