The first computer my dad had was an Amstrad, in all its green-and-black glory. They were good machines those! They used them on oil rigs in the early 90s. I used to repair them a lot in my Saturday job in a computer shop in Aberdeen, mostly replacing disk drives that had been gunged beyond repair. The only thing that went wrong with them was the rubber band in the disk drive wore out or broke. You could replace them, or pull up the adjuster just like tightening the fan belt on a car. We got one that had been hosed down with sea water when the deluge pumps had kicked in due to a false fire alarm. I washed all the salt off the bits with clean water and dried it out, and to the great surprise of all present, it worked perfectly when I put it back together. Truly the Toyota Hilux of the computer world.
