January in Mississippi can be nice
This pilot fish has January vacation plans: two weeks in Florida to visit his grandparents and take in Miami Beach.
What’s going on before then is that the manufacturing company that fish works for is converting its IBM Series/1 data-collection mini-computers from the EDI operating to a variation of Unix System 3. And there are problems. This variation of the OS doesn’t recognize disk packs with bad sectors. Fish’s company is using CDC removable disk packs, and if any sector is bad, the entire disk pack can’t be used. That can get expensive.
Surprisingly enough, the first several plants that get converted run fine, but the luck runs out with a plant in Mississippi, which has problems with bad sectors. Still, fish has learned enough from the IBM and CDC field engineers that he can run most diagnostics himself and assign bad sectors. Everything should be fine: The vendor for the OS is working on the code, and when fish comes back from vacation, they can install the new version.
