Problems in polar regions
Well, the worst situation I ever encountered wasn't in a purpose-built computer room. This was back in about 1983, and I had developed a system to log radar data from an airborne ice-penetrating radar for use in Svalbard. State of the art at the time - an S100 bus Z80-based single card computer! No OS, of course; everything had to be programmed in Assembler, and my development system was an Osborne 1 with Wordstar, asm and link - remember them? All was well in the office in Cambridge, but of course, it wasn't quite as we wanted it when we went off to the polar regions, so we took the development system with us. No problem - the Osborne 1 was (just about!) portable.
Unfortunately, the room we worked in had a nylon carpet, and of course, the humidity in the polar regions is extremely low. It was so bad that every time we brushed against a metal filing cabinet next to the door, we got a serious spark - enough to sting! It took a few goes for me to remember to touch metal BEFORE touching the keyboard of the Osborne 1; if you didn't the poor little thing just died. Fortunately, the whole setup was such that I always saved stuff (to floppy discs!) at regular intervals.
