- | Back in the day, computer architecture and topology was very different. One of my WANG clients held on to their equipment well past the ‘best before’ date. I understood why though, it suited their needs and they paid a lot of money for it. The problem they ran into was that WANG stopped supplying parts and had moved on to bigger and better things (well, WANG filed for bankruptcy too, but that is another story). The issue was boards for those huge bad printers and things like the terminals. With usable parts in our stores growing less by the week, we had to make a plan. Turned out that those boards were really easy to fix, a capacitor here, a transistor there. Suddenly I had switched from field support engineer to board repair technician. What I knew about board repair was scary! If I could not find the error, I would start replacing parts to see if the outcome changed. Just to be fair, usually it was obvious, popped capacitors or open transistors. Move the clock forward like 20 years and I bought a nifty AMD graphics card. I moved and, somehow in the move, one of those surface mounted resistors came off. I did not know the value and could not repair it. Basically a few months' | + | Bienvenue de retour dans un autre épisode de Questions et Réponses |

A: Just a quick note about terminals: they are actually terminal emulators. Some allow reading of the clipboard with ctrl+v and some you need to right-click then paste. If the terminal you are using does not allow what you need, you can use another. | A: Just a quick note about terminals: they are actually terminal emulators.
