Floppy holder
I had to laugh about the floppy holder. Years ago when I first graduated college, I studied electronics technology and computer science. I went to work for Tandy fixing there PC's this was back in 1982, so equipment was fixed to component level. Floppy drives were 500 dollars, so you put an o-scope on them and aligned them. I got a computer with a set of 4, 5 1/4 floppy drives in, the compliant was they would not read the disks. So I put the test floppy in to generate the cats eye pattern. They all looked pretty good and were within spec. They all did read write fine, so just in case I brought them as close to dead on as possible. 2 days later there back on my bench again same compliant, I check them again, everything is right where I set it. So I ask the customer to bring in a few disks. They bring them in and they work fine on the bench. The customer brings the computer back to the office. later that day the customer calls and says the problem is back. OK I can't duplicate this on my bench time for field service. I got to the clients site and there's his secretary mad as a hornet telling me I must be the stupidest tech on Tandy's payroll if I can't find such an obvious problem. I said I could not find it on my bench and her boss saw no problems with the drives on my bench. I said to her please show me whats happening, so I can see the failure. She says I'll show you there broken, she reaches over to get a floppy she had on her desk, that was leaning against her big magnetic paperclip holder. I tried to explain as politely as possible she was erasing parts of the data no the disk by leaning it against a magnet, and that it was explained in the manuals that the disk should store away from magnetic fields. Funny I never got another service call on that machine.
