Nothing speaks to an old computer better than a dedicated glass terminal.We enjoy [Adam’s] Restore one Acorn CRT monitorThe monitor is old enough to have that retro vibe, but it is not old enough to look like an antique.
There is a common problem with 14-inch monitors: the power switch fails. Of course, it should be no big deal to replace the switch, but these old CRT monitors have internal excitation voltages, so you need to be very careful.
For example, a common problem is that old CRTs are very large capacitors that can hold a dangerous charge for a period of time. The easiest way to deal with potential problems is to ensure that the device is unplugged, ground the screwdriver blade, and then push the blade under the second anode cap. Most of the time, nothing happens. However, occasionally, you will hear a loud noise, and you just avoid an annoying shock.
Although the actual maintenance is ordinary, the disassembly is a great nostalgic journey. Although we don’t want to give up our LCD, we do like old glass.
CRTs have a long history and have come a long way before they took their last breath. They even take turns as mass storage devices.
