[ Home | Vintage Computer Collection | Projects ]


With vintage computing hardware you are dealing with older machines with possibly many power cycles of the electronics. Old capacitors die and seem to be the culprit behind the early death of power supplies and monitors. In order to keep machines in running order you will have the occasional need for circuitry repairs simply due to age. If you are not careful in handling older electronics, a static discharge could also do something nasty to the electronics. Repairs may be needed if you make a mistake or a previous owner was careless.

This is a list of maintenance and expansion projects related to my collection. A maintenance project involves anything from testing new additions to the collection for faults, performing routine maintenance on existing hardware, or repairs on existing hardware. An expansion project is generally one of building an interface between older hardware and newer hardware. This might let you use your PC's hard disk for a boot image of an older machine by emulating its drive interface.
