Full of incredibly tiny electronics, but for automated manufacture, many are in modules joined by contact springs instead of solder or connectors so many parts come right off. Small speakers, mic, power connector, SMD bulk caps occasionally, tiny eccentric weight vibration motor. A few models have display modules you can find specs for. | Full of incredibly tiny electronics, but for automated manufacture, many are in modules joined by contact springs instead of solder or connectors so many parts come right off.

Power supply is useful as a unit, or can be taken apart for transformer, caps, diodes, and similar. Many have a filtered input connector which is rather valuable. There are usually some LED and switches on the end of wires that plug into header blocks. They also may have CD DVD Floppy Drives see separate discussion. The connecting wires are often useful, sometimes taking the connectors off the mother board makes them more useful. Individual boards may be useful as they are. The mother board is not usually useful for its chips, most are too small and specialized for much use. Crystals may be found, not sure if frequencies are useful. AT-era PC's often had D-connectors of both sexes on ribbon cables and peripherals have matching cables. Some have RTC modules, others have CR2032 lithium batteries. The big BIOS flash/eprom may be recyclable. Certain vintages have nice SRAM chips as cache. SCSI and other smart controllers have serial eeprom's for settings. Old ethernet cards and cables yield 50-ohm coaxial wiring. Loads and loads of screws in the case. | Power supply is useful as a unit, or can be taken apart for transformer, caps, diodes, and similar.

Card slot if you can get it out. Battery, contacts and charger. Switching regulators. Very nice displays but hard to use. Be on the lookout for EL backlights, though, if you can power them. Nice smooth squares of very white light. Optics of varying types, connectors if you can get them out. Marvels of miniaturization and cramped-space engineering worth looking at in any case. | Card slot if you can get it out. Battery, contacts and charger. Switching regulators.

Often have stepper motor and Brush less motors. The old 5 ¼ drives are most likely to have reasonable power steppers. most of the chips then to be too small and specialized for much use. The 3.5" power connector is reasonably easy to remove with most equipment. | Often have stepper motor and Brush less motors.

High voltage transformer ( dangerous ), high voltage capacitor and diode. Good magnets in the magnetron tube. Lots of micro switches. Small motor, motorized fan. |

Often have stepper motors. Plugs, jacks, power transistors, diodes. Gears, shafts and other mechanical components. Control panels may have led's and push button switches. Many laser printers have standard type LCD modules. Many inkjets have nice big external power supplies. | Often have stepper motors. Plugs, jacks, power transistors, diodes.

May not be a good salvage candidate: There are high voltage dangers and dangers from imploding picture tubes. Also when you are done there is often a disposal fee as the picture tube contains a few pounds of lead. Do not dispose of irresponsibly. | May not be a good salvage candidate: There are high voltage dangers and dangers from imploding picture tubes.
