Re: Slack
In the aftermath of the Loma Prieta quake of 1989, many Silly Con Valley companies discovered that leaving slack in the cables is a good idea in Earthquake Country. I have no idea how many backplanes were ruined, nor at what cost, after having their lovingly screwed in cables ripped out without so much as a by-your-leave. I do know that 19" racks full of screwed up equipment were extremely common for several years at places like Haltech, HalTed, TheSource and Wierdstuff ... I managed to cobble together a lot of good gear out of "scrap", at scrap prices. Most of it still works.
Hey, we warned 'em ... but who listens to the natives?
