I have been asked to try to find out if there is any salvage value in the
disk stacks in a CDC computer.  The model # is 883-91 and they contain about
10 platters.  

Any info is appreciated.

Simply connect the speaker in series with a variable resistor of
maybe 10 or 20 ohms.  Speaker volume is a function of current, and
the speaker output is constant voltage.  At you increase the
resistance of the added potentiometer, the current flowing through
the speaker will decrease, leading to lower volume.  At minimum
setting (0 ohms), the speaker will be loudest.

Why don't you simply run the rf signal into your vcr, then audio and
video out to your monitor?  There are such devices, but usually just end
up using the tuner in a vhs deck because it is handy and relatively
inexpensive.

I need to build a Hold circuit for a phone line.  It would simply allow
me to put the line on 'hold' and once having done so, I would be able to
hang up the phone, or even unplug it, and still not lose my connection,
so that I could come back to it.
 
Also, if anyone knows how to do this easily, I would like to build a
multi-line adaptor for my single line phone.  It would basically do what
those fancy office phones, with the row of illuminated buttons do -
allow me to tell when a line is ringing, answer it, and still be able to
tell/answer/and switch to another ringing or waiting line... Anybody
ever done this?  Thanks a lot.

Yes and errr, no. We couldn't find any socketting system which would
fit [1] to [2], so we cut a 0.1"x1.0" groove in the w/w board for
each socket. This allows one side of pins per socket to remain "hole
resident" whilst the other side fits in the groove.

Your next question is "where do you get w/w zip sockets?". Again we
couldn't so we used w/w sil strip + super-glue to make some
customised jobbies. (Yes, it did work quite well).

You will have some clearance problems if you have a lot of w/w going
to the pins since [2]'s spacing is (umm, thinks) 0.7 of [1]'s. This
will be esp. true for a *fast* Dram array where you'll have to
also wire bus-bars and decoupling caps for VCC and GND.

Next week - how to make a w/w DEC Alpha socket out of punched-cards
and paper-tape and a page-mode Dram controller out of F-part TTL.

Good Luck! (let me know how you get on).

I dunno but this is the way I think it is supposed to be for a proper null
modem cable with out disabling your rts and cts and all them goodies :)


2 goes to the other 3
3 goes to the other 2
4 goes to the other 5
5 goes to the other 4
7 goes to the other 7
8 goes to the other 20
20 goes to the other 7

This one should work but it is not guarranted to work for a sure thing
but you lose the auto hang up and things you can try....

2 goes to the other 3
3 goes to the other 2
4 jumpered to 5 on  both sides  (as in on the same end of the cable)
6 jumpered to 8 jumpered to 20 also on both sides
7 goes to the other 7 

and well if these dont work give up like I do and call someone *grin*

You have probably never soldered *without* flux.  The rosin core in
ordinary electronic solder is the flux.

The purpose of flux is to clean the metal that you're about to solder to.
The idea is that the flux melts and gives the metal a quick cleaning,
flowing just ahead of the solder.

BUT I hope that when you used a separate flux, you used a kind that is
suitable for electronic work!  The kinds used in plumbing (zinc chloride,
etc.) are not reliable, over the long term, in electronic gear.  They
have a nasty habit of continuing to corrode over the years.  This wouldn't
be a problem in plumbing, where the soldered joint is _big_, but in
electronics, a millimeter of crud isn't tolerable.

Followup-To: poster
Organization: Hewlett-Packard VCD
X-Newsreader: TIN [version 1.1.4 PL6]

I have the need for a simple audio mixer for two (would like three) line-
level sources and one microphone (but two is OK.)  Radio-Shack sells a
unit with Vu meters and sliding faders for about $80 that ALMOST does the
trick - it has a single line-level input and two phono inputs.  The phono
inputs have both ceramic and moving magnet inputs.  I'm wondering if 
there's some way to take apart the RS mixer and convert either of the
inputs to line-level.  (Or is that the purpose of the "moving magnet"
inputs?  I never got into details of phonographs...)

So... what I'd like to know is how hard is it to convert a phono-style
input to a line-level input?  If it's relatively simple, I can use the
RS mixer.  If it's a big deal, can anyone recommend an inexpensive mixer
with 2 or 3 line level inputs, 1 or 2 mike inputs, Vu meters, cue 
functionality, etc?

Any help, ideas, or suggestions would be greatly appreciated.

Best regards,
Ed

Subject: converting one-hot encoding to binary
Organization: Advanced Micro Devices, Inc.
Date: Tue, 13 Oct 1992 17:22:44 GMT

I have a string of 64 bits which is one-hot encoded, which means that
each bit represents one on/off state of one physical unit.  I want to
convert these 64 bits into a single 6 bit representation.  The 64 bits
are stored in a 64 bit circular shift register.  The string starts out
cleared to all 0.  Then a string of 0111...1 is loaded into the shift
register and is shifted around, thus on the next clock, the string
will be 1011..1, then 11011...1, etc.  Thus there is only one bit which
is 0 at any one time EXCEPT when the registers are cleared to all zeros.
I want to map the all zero state to 000000, 011111 to 000001, 101111 to
000010, etc.

I know this can be done combinationally/with a PLA but I was wondering
if there was a better way since the number of combinations is limited
in that there can only be one 0 in the string except in the all zero 
case.

Any suggestions welcome.  Thanks.

Take a look at RUN/EDS (from formula, in germany) - for board layout
it blows most of the other stuff out of the water. I use that combined
with 3.0 designworks (beta) to do my stuff. Designworks is the best
you can do if you want a capture and simulation system, if you JUST
want capture, then ECS makes a better thing - it's supports simulation
on verilog or synopsis but not internally. I tried McCad and Protel
and they where just too toyish to support my needs. RUN also makes
a design capture tool, and it's definatly worth looking at if you like
RUN/EDS. It has some unique features - like allowing you to open both
schematic and layout at the same time and AUTOMATICALLY updating
changes you make on one to the other in either direction. Neat. Douglas
CAD is excelant if you wish to do you all your own layouts by hand. Their
autorouter is for the most part useless. - But the PCB editor is 
probably the easiest I've used.

Here at Cypress, we have 2 x16 EPROMs: the 16kx16 CY7C270,
and the CY7B210 64Kx16 EPROM (my part! :)

Since package area is an issue for you, you should know that both
are available in 44 lead surface mount packages. (i.e. windowed
leaded chip carriers). The other package option for x16 EPROMs
is a 600 mil 40-pin DIP, which occupies a space about 2" by 5/8"
(5.2x1.6 cm) The 7B210 is available in the DIP package.

These parts are both very fast: the 7B210 is sampling at 25 ns,
while the 7C270 is 28 ns for random access, and has a 14ns clock
cycle in BURST mode.

Hope this gives you a reasonable alternative. There are other
x16 EPROMs out there, but ours are the fastest!

A quick question:

Do Nickel Metal-hydride batteries exhibit the same "memory" that NiCads do?

Please e-mail, as I am not a regular reader of this group.

Thanks.
