So that's where that term comes from! I've heard it in American movies / TV
and read it in books but couldn't work out how a bottle that wasn't much
more than a pint (~600ml) got the name 'a fifth'. I forgot about the Merkin
gallon being less than a real gallon. In fact it's almost exactly 'a fifth'
short!

Nah that is what the rest of the world called a 26oz bottle before metric.
Of course in the US that would be closer to 25 fluid ounces. <shakes head>
US water must be heavier.

A pint's a pound the world around!

"Voluntary conversion" is doomed to failure due to inertia so it's a failure
of the legislators not the public. It should have been made compulsory as it
was in most other countries which changed over.

Ok second guy in this thread to use the term "English units". Am I to assume
it's an Americanism then? In England, Australia and New Zealand (the
countries I've lived in) non-metric units are reffered to as "imperial".

The top-posting should have given you the clue you needed there....

No, jews are good at finance because the catholic church banned christians
from usury - lending money and charging interest. As money became more and
more important it became necessary for there to be financiers but christians
weren't going to risk lending their money free of charge. So jews were
invited into most catholic / christian countries to be the financiers as
they had no such rule in *their* holy book. Without jews stepping in to
finance large projects we'd still be in the dark ages.
 
Yet how do we thank them? By making thinly-veiled anti-semetic jokes in
electronics repair groups (and probably other places as well).

Further to this, Circadian Rhythm is very approximate, that is, it adjusts with the seasons, day/night length, temperature, in some cases the phases of the moon, and more. Try setting train schedules from a process that may alter by tens of minutes on any given day.

You could have pointed out that is what the "circa" means!

Much as I hate to ask the obvious, but have you tried Hitachi directly? I have found that OEM, if approached gently, will often go to considerable lengths in response to such requests.

That was very much my experience when, years ago, I bought a "board
(=PCB) camera" from them. They supplied some s/w to drive it and the
interface specifications so I could build my own.

Hi Trevor. Trust you are well ?
 
Well, yes. Why bother indeed ? It's old, and its only 10 MHz. But it
belongs to a guy that supplies me quite a bit of work, and he said it
was a shame to see it go in the bin if one or other of us could fix it.
So I took it back to my workshop, and it has sat there for a couple of
weeks. This week, the 'paying' work is dire. I might as well not be
wasting the money on the electricity ... So I figured I'd have a quick
look at this scope. I kind of think that it might be a power supply
problem. Basically, there's no display, although the tube heater is up,
and the tube face lights up with a store flood or erase operation. The
calibration square wave is present, and if you stick that into one of
the Y channels, you can follow the signal some distance down the
amplifier strip. But here's the thing. There is no scale illumination
when you turn the pot up. It appears to be four somethings - probably
LEDs but maybe bulbs, you can't really see - wired in parallel around
the graticule. I can't see much in the way of volts at them, but it's
all a bit hard to get to without a lot of dismantling.
 
So I figured a quick squint at a schematic would soon tell all. Rail
missing or red herring ? So I went looking, and was amazed to find
nothing for it online.
 
I might try Hitachi direct as Peter suggested above, but these days, I
don't think I would hold my breath that anyone there would be prepared
to spend the time digging through archives to try to find what I need.
still, you never know ...
