Our people fitted a new central process control unit in a plastic film factory. This had just about every test imaginable before being fitted including being hit by brownouts and static discharges. However, once installed at the location demanded by their engineers all sorts of random errors were occurring. This was in the middle of the factory on a partition attached to the back wall and at the top of a flight of steps. It was months before we identified the problem, and only then because one of our engineers took a laptop there to make notes of readings and it kept crashing. One of their production workers commiserated and said that their mobile phones would sometimes freeze if they went there. In a moment of inspiration our guy asked what the partition was there for, and was told the 3 phase supply for the entire factory complex was behind it.
A communications problem
Customer: {mumble} {mumble} {complain} getting worse {mumble} You fixed the last one so why can't you do this one?
Us: We would if we could get the parts. Most of the chips on the board have been obsolete for years. We just can't get them anymore.
C: {woe} {woe} But the machines have years of life left in them.
U: Well, as we suggested before, we could always fit modern controllers to them as they fail. This could actually work out cheaper than trying to fix the old ones.
C: No, you'd have to do all of them at once and I can't afford that.
U: Why would we have to do them all together?
C: Because they all have to talk to each other.
U: Well, modern controllers can be configured to talk to the old system.
C: No they can't. There's this special system installed by Radiospares.
U: Pardon?
C: The machines can only talk to each other with this. There's some board or something fitted in all of them.
U: {collectively scratches head and asks around} Can you be more specific? None of us know of any system that Radiospares have designed, and we have never heard of them doing installations.
C: {smugly} Well it *is* an old system so I expect you young engineers haven't have come across it.
U: Does it have a name or anything?
C: Yes of course, and a model number. It's the RS-232
A place I once worked for had a system of route numbers, not cable numbers. This was for highly distributed Audio/Video systems, so you'd see a number on a balanced audio patch panel and the same number would appear on all cables and interconnects right up to the mixing desk. With almost all bundles, there were also a few unconnected lines with a totally different series of numbers.
Sitting on my desk is a home-made amp with FM radio. I built the lot from a mixture of available drawings and my own ideas. That was in the early 1970s. It's been pretty much in daily use ever since. The only change being a replacement volume control a couple of years ago. I could probably still get the parts for, and fix anything else that might go wrong.
I wonder if anyone could home-build a DAB radio? Any takers?
