there any way to add (build or buy)
progressive scan to the TV so it can
use the enhanced output from a DVD
I picked up a Zenith TV — model
H2017Y — from a hotel that was
remodeling. I can’t get the AV inputs
to work; it looks like some
programming or setup is required. I
have no owners’ manual and would
appreciate any help.
I seem to remember an Internet
project a few years back for adding a
"tachometer" to a PC, via an
automotive needle/meter tach, so I
know it must be possible to do it.

When the BePC came out about
10 years ago (remember those?),
there were two vertical columns of
LEDs on its front panel. One lit to
show CPU activity level; the other
showed (I believe) memory activity. It
was quite a show! I'd like to make
something like that for my PC and I
wonder what would drive the meters?
I have a vacuum pump that uses
four D cells in series for a total of 6
VDC. I want to build or acquire a
battery eliminator for the pump. How
do I determine the amps required for
the pump? The unit has a PCB with a
NEC D882P, an IC that has had the
markings sanded off, and various

I got a new computer with
WindowsXP on it. (My old computer
had Windows 98.) I use a DOS
program to communicate with a PLC
(programmable logic controller)
through the serial port. The DOS
program loads and works, but it will
not communicate through the serial
port. Different settings have been
tried, in addition to Windows 98
compatibility mode. The program
tries to communicate with the PLC,
but it times out. If I unplug the serial
cable, it gives a communication error.
How do you get the XP serial port
to work using older programs? Is
there a way to get to a C:\ prompt
before XP loads, like in 98? Can the
hard drive be partitioned in XP and
use 98 for older programs?
The manufacturer of the software
does not have an answer, but they
want to sell me new software that will
run under XP — though they removed
the features I use the most.

I need help on a phone problem.
I just installed new AT&T 2.4 GHz
phones: a base and three handsets.
Now, if all the phones are in their
charging cradles, I get big double
horizontal bars on TV channels 4 and
5 and buzz on my portable FM radio.
If the phones are out of their cradles,
everything is okay. The manufacturer
could not offer any advice, but I hope
someone here can!
I've just picked up a couple of 6"
neon light tubes that I want to put into
my PC. The tubes were sold for car
use and have power converters — 12
VDC/150 mA in, 1,000 V/15 mA out.
I could buy a module that will "blink"
the lights to music, but I want a
