Скачать или смотреть Another Acorn Archimedes A3000 Repair Vlog

A pretty detailed video log of an Acorn A3000 repair. The machine was purchased from Ebay and was apparently recovered from a skip years previously. It was in very good cosmetic condition but had several faults and would not even POST or boot initally.

The video covers the fault finding process, using the the service manual, schematics and an oscilloscope to get the machine to boot.

After that, the floppy drive, power supply, keyboard and mouse controls are serviced and/or repaired.
