What do I do when I find terms such as initrd or udeb ?
Hi Richard,
You may have already found your answer but here are a few links I
discovered that may provide additional support.
I got the answer to the question I was _trying_ to ask. But
the more links the better for those who come later searching
for similar information. On their behalf, I say "Thank you."
In regards to udeb:
http://lists.debian.org/debian-devel/2000/12/msg02118.html
http://www.fileinfo.com/extension/udeb
In regards to initrd:

And before I get too much grief from youngsters - From personal experience
do you have any clue of relevance of CORC, CUPL, WATFOR, WATFIV, 026, 12AX7,
etc, etc ;/ ?
Ah yes...I am also from the era when vacuum tubes ruled the earth! I
had 12AX7's in my Dynaco stereo 'pas 3' pre-amp and currently in
numerous tube guitar amps. 12AX7's are also known as ECC83.
Basic 12AX7 specs (not complete):
High-MU Twin Triode
Each triode unit is independent of the other except for the common heater.
Used as Phase Inverters or twin resistance coupled amplifiers in radio
equipment. Also used in stereo and musical instrument amplifiers.
Heater voltage: Series 12.6 volts Parallel: 6.3
Heater-Cathode-Voltage:
Peak value: +/- 200 volts
Average value: 100 volts
Class A1
Maximum ratings (Design Maximum Values)
Plate voltage: 330
Grid voltage: 55
Source: RCA Receiving Tube Manual RC-30
But you missed the computer related application.
They served very nicely as active element of *FAST*
flip-flops (MEGAhurtz)
IIRC they were building block of circa 1950's IBM CPUs ;)
(Can any one say pre-RX01 11/45? )
(or know what resided at ML5-5?)
I suspect this group is basically just to young to
appreciate 'ye good ole daze' ;)
You haven't lived until till you've flipped front panel
switches to load your high speed paper tape reader routines ;)
Be well Richard
Wally
