Totally contrary to every KL10 I've ever seen, and
all the
published maintenance documentation. There's an individual
fan on each heat sink, and they are arranged in a
rectangular fashion. I really don't believe that DEC built
a special version just for you. Both the KL10-A (earliest
version) and the KL10-E/R (lastest version) used exactly
the same H861 regulator assembly.
Well, that's what 35 years will do to your memory! I guess
I'd better stick to
11/45, 11/780 and uVAX II, which I worked so much with that
I won't get much
wrong.
Jon
was not greatly different, but they reduced the
number of separate regulators and I
think cut one whole regulator board out of the system that way.
They never
eliminated any ECL regulator board. All KL10s have nine
5.2V regulators and four 2.0V regulators. The only thing eliminated
was the tenth 5.2V regulator, which was never used in any KL10 model.
