Ardnamurchan Point to Cape Wrath: North or northeast 3 to 5, becoming variable
2 at times. Slight or moderate, becoming smooth or slight between Barra and
Canna. Fog patches. Moderate or good, occasionally very poor.
I'm sure
everyone here knows this, but the Cray 1 (I think, the one
that had what looked
like a circular bench seat around the bottom) was
designed like that because the clock was at the center and the clock
signal went to all the boards and was right because all the clock lines
to the boards were the same length.<
you mean that?

After going down that rabbit hole (thanks!)...
I love the motor/generator pair(s) they used to power the thing. I
immediately thought of a motor-generator set my father had, to turn 60hz
into 400hz, so he could test products they built at a defense contractor
(and later, NASA contractor).
Sure enough, the Cray used 400hz AC input power.
