A heaping plate of spaghetti, a glass of red wine, and warm glowing toobs

I'll let you guess what's in the metal box. Kind of a mindf**k as
"tubescope" goes, but it works for me :)

P.S. Oops, make that two glasses :)

I have one of these dealies sitting under my workbench a friend gave me,
I've been tempted to build some kind of project out of it:

http://www.radiomuseum.org/r/hickok_oscilloscope_os_8bu.html

Unfortunately it smells like a battleship! Cosmoline or something like
that. Every time I take it out of its protective housing it stinks up
the entire room, and it's even worse when I turn it on and it warms up!

Me too! Rifles are covered in the stuff for long-term storage so the
metal parts won't corrode. Wiping with a rag soaked in mineral
spirits will remove the cosmoline.

I remember reading a quite a while back about a method used for
generating letters and numerals on a CRT done in the pre-microprocessor
era completely in analog. I can't remember if was based on Lissajous
figures exactly; all I recall is that sine waves were fed into
complicated looking LCR networks that produced appropriate phase shifts
in the X and Y signals fed to the CRT to generate various curves, and
these curves were somehow multiplexed into the correct figures. I wish
I could remember what book I saw this technique in.

The manual says the vertical amplifier has a DC bandwidth of 0 to 2
megacycles, AC bandwidth of 5 cycles to 2 megacycles. Horizontal
amplifier is the same except only to 500k cycles.

My HP9100 programmable calculator, made from transistors, no ICs, had
a CRT display. 7-segment, scanned strokes, electrostatic deflection.

I still have two 9100s. Gotta get them working one day.

Cute! Not many tubes, possibly just enough for differential drive?

The BK this scope *used* to be was pretty terrible. Three compactrons on
a PCB, a late model TV repair scope. SE deflection and really awful
linearity (RC sweep). So, I don't even have a sweep circuit yet and I'm
doing better. :)

Yes, it looks like it has differential drive on both the horizontal and
vertical amps. 8 tubes, not counting the CRT and rectifier, all tightly
crammed in there in little modules. It would probably be a good scope
for hacking because they're nice enough to bring the connections to the
CRT plates out to jumpered terminals under a little flap on the back,
and it has an intensity input as well.

There's a full schematic in the user manual here:

Scope looks nice, you need some 'flyback' suppression in your timebase.
(intensity lower when sawtooth returns).

Somehow I find that little machine more impressive than the latest intel

The "32768 bit ROM board"... no not a chip! A 16 layer PCB with
orthoganal drive/sense lines... is the board material itself magnetic
somehow? No, just lots of little PCB mounted cores I suppose.
