Then there were "hybrid" car radios.  The AM radio in my Mom's '62 Cadillac
(and several years before and after) was of this design.  Tubes were used in
all stages except the audio amp.  Since the other stages don't need much power
they got away with using just 12 volts on the plates!  The audio output stage
was a single power transistor, with a Delco part number, hung on a heatsink at
one end of the unit. 

They weren't alone in these bizarre practices either. _Popular Electronics_ ran
a couple of construction articles for "starved circuits" -- tubes with just
twelve volts or so on the plates -- in the mid-60s, I believe.  (Couldn't have
been much earlier, I only started reading PE then!) 

The same Caddy car radios had a bizarre design for a band-scanner:  A spring 
provided power to tune up-band to the next station.  When it hit the high end,
a pair of contacts would close, causing an electromagnet to yank it back to the
low end and rewind the spring.  Maybe running a motor during band-scanning 
would have made enough RF noise to fool the station-seeking circuit (DC 
brushless motors not being common back then!).  

Excuse me, I need to comb the snarls out of my long, grey beard.

Open up your remote transmitter and see what it's made of. If you're
lucky enough to have one based on SAA1250, it is very simple - no
carrier, just 10 us pulses either 100 or 200 us apart. Very easy to
get a readable picture on a scope (and emulate by software). It is
rather popular especially in European products.

Get the data sheet for details. I have some remote controllers which
use the SAA1250 scheme, but have been implemented with small mask
processors. Probably cheaper that way.

  I currently have an old 19" computer monitor which has 4
BNC inputs Red, Green, Blue and Sync (Composite that is).
I understand that the horizontal and vertical sync signals
are negative. I would like to build a circuit which allows
me to drive this monitor from a standard VGA card. The 
problem is:   
           1) the VGA sync signals are positive 
           2) the VGA 15 pin connector has seperate horizontal
              and vertical sync signals

I need to invert the sync pulses and superimpose the two
signals (horizontal and vertical sync) into a single 
composite signal. I have no information on the pulse width
and amplitudes of the sync signals. Is there any information
available out there for computer monitor signals? Are there
any IC's which will drive these signals? Any help is much
appreciated.

Absolutely. Nearly every type of consumer electronic equipment is
susceptible to interference from EMI. A nearby transmitter can cause
all sorts of problems in telephones, audio systems, computers, televisions,
VCRs, radios, alarm systems, lighting devices, intercoms ... the list 
includes nearly anything electronic.

Transmitters must also be shielded against the emission of signals that can
be the direct cause of EMI. In addition, many of the devices cited in
the first paragraph, plus a host of others, can be the source of interfering
signals. Possible EMI sources that should be shielded include: electrical
power systems, computers, motors, thermostats and switches, transmitters,
automotive ignition, etc.

In addition to shielding, filtering techniques can also be used to minimize
the unwanted interaction that results in interference.

The American Radio Relay League has a free handout about EMI called the
"RFI Package." (Send me email, including your postal address, with a 
specific request for the RFI Package.) We also publish a book about
EMI "Radio Frequency Interference - How to Find It and Fix It." Contact
ARRL for information about products and services.

I'm rather surprised by this.  Who'd want to build a MacroVision remover

Congratulations.  You just (re)invented the vibrator.  This was how
car radios worked in the pre-1960's.  An electromagnet vibrator
did the switching.  Coincidentally, I just dumped the last of my
vibrator stock tonight.  I can't imagine needing replacements in
the foreseeable future.  Vibrators were pretty reliable, all things
considered.

X-Maildoor: WaflineMail 1.00r

Hi I'm looking for something like the NCR 5380 SCSI controller?

Is this chip "fixed"?  Someone told me that they did not follow
the spec properly in the Automatic/DMA mode for SCSI.  What they
said was that in REQ/ACK handshaking it sent an ACK before it
recieved an REQ, and it did not follow the timeing specs.  If in
Programmed IO mode it worked fine.

Has this been corrected or are thier other chips available that
are fully compliant to the standard?  I don't need GREAT speed
but I don't want to have to put a dedicated processor for just
handling SCSI IO.  Though it might be cheaper.

ALSO where can I get a hold of a 74F653?  This was recomended
instead of using the NCR5380, and using a dedicated micro
(controller/ proccessor) to perform the actual SCSI IO.  Would a
Z80A be able to do this?  Or would a 68B09 be better?  Or
something like a 6805?
