I would hardly call Tony self-righteous. He does have strong opinions
Thank you.
and lives by his convictions, but I have always got
the clear impression
Indeed I do have strong opinions, but I try to have reasons for them. For
example, I object to random board-swapping because there are logical
reasons why it can give the wrong result. I promote component-level
repair (and even repairing components in some cases, like rewinding
motors) because that seems to be the only way to keep an old machine
going -- you can't get known-good replacement assemblies any more.
Similarly, I do feel tha the PSU, and even things liek fans, are part of
the design of the machine, which is why I like to keep the original
circuity wherever possible. For example, the PDP1/44 (And some 11/24s)
use strange fans running off a 35V 70Hz AC supply generated on one fo the
PSU boards.
Of coruse plenty of other thigns will cool the machine just as well. You
may feel that replacing the fans with 12V DC ones and runnign them off
the memory supply is acceptable. To me it isn't, that fan circuit is very
much part of the deisgn. So I would take the time to replace bearingsi n
the fans, even rewidn them if I ahd to. But in the end it comes down to
the owner of each machine to decide what he wants to do.

In some cases. However, I hope I also give an alternative. I don't think
I've ever simply replied 'damn boardswapper!' and left it at that, unless
I've put a smiley on the end. I will try to suggest tests and repairs to
find the fualt.
that the connotation
"especiallywhensmuglymoralisticandintolerantoftheopinionsandbehaviorofothers"
of the word "self-righteous" (from
dictionary.com) applies. Being
intolerant is not the same as disagreeing and trying to convince people
they are wrong. Intolerance implies refusing other people the right to
their opinions.
Of course. Here, I'll state it : You have the right to do what the heck
you like with your own machines. You have the absolute right to disagree
with me as much as you like (of course I also have the right to disagree
with you). However, disagreements are much more useful when there are
reasons for it.
If I say 'You're an idiot for wanting to replace the TRS-80 power brick
with a PC power supply' and leave it at that, I think it helps nobody. If
I say 'Because of the design of the TRS-80 model 1 -- that the PSU
regulators are on the main logic board -- it's difficult to use a noraml
PC power supply to power this machine. However the power brick onlt
contains 4 components, so it should be quite easy to sort out...' (and
then go on to explai nthe design), then you have some infromation which
you can use to decide what to do -- whether to modiy the TRS--80 to take
in regulated voltages and use a PC power supply or whether to attempt to
repair the brick.
