The number of platters differed from one type to another, but the most common had eleven platters, and twenty heads (the top of the top platter and the bottom of the bottom platter were unused; between each platter there were two heads, one facing up and one facing down). When not in use, the disk pack is stored with a smoked plastic cover that screws onto the top, and a (usually) black plastic bottom cover, thus keeping dust out of the pack while it's stored on a shelf. The top has a built-in handle in the center. + + Hard disks are top-mounted, like a (traditional) washing machine, and were typically a similar size to a washing machine. Sometimes they were mounted in drawers within a rack, so the entire unit would slide forward. + + Disk packs weigh in the range of 10-20 pounds, depending on the number of platters, etc. + + To insert a disk pack into the disk drive, you typically squeeze a lever or slide a cover to open the door. Assuming the drive is empty (and if not, see below for removal), holding the disk pack by the top handle, use your other hand to remove the bottom protective cover by squeezing in the center or unscrewing it. Gently lower the pack into the well in the center of the drive, centering it. Turn the handle counterclockwise until it stops turning easily. Do not overtighten, or you can damage the pack and/or drive. Pull up on the cover (which will release itself from the drive when sufficiently tight), and put it on the base (removed earlier). Close the door of the drive, and push the drawer back in if it's rack mounted. Push the start button. The cover and base are generally kept on a shelf near the drive. + + To remove a disk pack from the disk drive, push the stop button. Wait for the drive to stop turning - there's usually an audible "click". [If you're brave, you can open the cover while the disk is still turning and gently touch the center part - not the magnetic part - slow it down. Don't stop it to abruptly, or you'll break the pack. Disk drives of this generation spin at 3600 RPM ] When the disk stops turning, open the drive door. Remove the cover from the base (ensuring that you've got the right cover - they are usually labeled with a sticky label so you can find the pack again later). Gently lower the cover onto the pack, and turn the cover clockwise using the handle until it won't turn easily. Gently pull up (it may require a slight tug). Lower the pack and cover onto the base, and latch it to the bottom (usually by squeezing the center of the base). Put it on the proper shelf, and close the drive door. + + == Other references == + + * list other references about this skill here + + [[Comments]]

Commercially manufactured radio sets were expensive, and many people built "crystal sets" out of readily available materials. + + A crystal set radio consists of a very simple coil and capacitor tuner, a rectifier and a set of headphones. In early homemade versions, the antenna served as the capacitive element, and people wound their own tuning coils. The crystal set required no power - the rectified signal from a sufficiently powerful AM transmitter could drive headphones at enough volume that you could hear it. + + In early crystal sets the rectifier (or "detector") was a natural mineral crystal (commonly galena) with a thin wire called a "cat's whisker" which lightly touched the crystal, and actually formed a primitive semiconductor junction. This device was inherently unstable, and the operator had to continually adjust it to find a good spot on the crystal, and obtain the right touch with the wire. It took some practice to be able to do it consistently. + + Thus, we have two skills - building the thing, and adjusting the cat's whisker to be able to use it. + + If you wish to build a modern version, you will probably use a germanium diode instead of the crystal (around $0.20 each, but you'll probably have to buy a pack of them for a couple bucks).

The tape was a thin film of polyester and was quite tough, but over enthusiastic rewinding or jambing of the tape in the pinch rollers that carefully controlled its speed during recording and playback (otherwise the pitch would warble) sometimes led to the tape breaking. One would use a small metallic clamp to hold the ends of tape for cutting with a razor, then position them to allow a tiny amount of glue to be applied to the ends and rejoin the tape.
