[HECnet] TOPS-10 D-Day, DECnet failure on November 9th is less than six days away --> 10-nov-2021

[R. Voorhorst]

L.S.

Decnet still running here without bugs on 5 tops10 and one 4 Tops20 of which
1 is a Panda and 3 are even Tops20 V4.1.
So have to check the code if repairs were already in place a long time ago
...


Best regards,

Reindert

really did, particularly did because you had sit close to it to use the
GT40.  I don't remember an 8/E being that bad.

pile of KL's, KI's and a KA in it.  2116, 2012, 2136, 1031 come to mind, but
there had to be three times that list.  What a racket.

One of the nice features of CDC mainframes (the 60 bit machines) is that
they were rather quiet.  That's because the mainframe was liquid cooled,
with water cooling of the refrigeration machinery.  Only external boxes like
the console and outboard peripheral controllers had cooling fans.  The
machines I worked on had the disk drives in another room (one floor down)
which put all that noise away from the operators.  Being able to talk to
your colleagues without shouting was quite nice.
