Was that a "first of it's kind"?

Subject: Re: [AFMUG] Having fun
I was working Emergency Response Facility design in 79-80 after TMI.
DEC wouldn't sell to the nuc industry so we were doing Prime's. Wrote
my own networking code on top of their low level device drivers on huge
coax -LMR400- connections. My code, frankly sucked, but getting a 500K
throughput was so much faster than serial it didn't matter for the small
data sets we were sending. We also did some of the first fiber data
connections to get the data from the plant 1.5 klicks to the ERF. That
was an interesting opportunity, specially when I,we almost caused the
operators to start a shutdown. It wasn't really close, but they though
about it before we figured out what was going on...

We used the Prime computer systems, never had a head crash with more
than just a lot of substrate scraped off, but remember getting a lot
of colds as a result of computer rooms at 65 degrees then going
outside into 85 degree weather...

Believe they were seven platter, and when a head "crashed"
it generally acted like pin-ball and took out all of them.
The tops of ours were light smoke color so you could watch
the "excitement" of all the heads and various parts bouncing
around with little you could do about it until the drive stopped
spinning (the top would not open, probably a good thing)...
