I'm posting this for a friend who doesn't have usenet access, so email
replies to me, and I'll get them to him.  Thanks.


We have FOUR CDC/4680 (MIPS ECL R6000) systems and all four go up and down
like yo-yos, have poor network performance (especially NFS -- gag!),
disk controller and ethernet board failures, CPU board failures, and so on
and on and on. CDC claims they have a total of 48 systems installed and these
are the only FOUR that have problems. We actually received shipment of SIX
systems, but TWO were irreparably DOA and had to be shipped back. A THIRD
was not DOA but had to be swapped out with a new box after about two months
of failed efforts to make it work. SO, since our experience is that SEVEN
consecutive systems shipped to us from MIPS, and installed by CDC with their
variant of the MIPS OS, were utter dogs, it seems hard to take CDC at their
word that the other 40-some-odd systems are happy-go-lucky.
