Hi NG.
anyone have a datasheet on the MB87F1720 Video ic?? it sits in a
Panasonic TX-W32D4F (euro 5 chassis.) need to have at least block
diagram over the IC.

I'm looking for a source for the above type of encoder.
Basically it's a serrated wheel (like the volume knob on a miniature
radio) but with detent stops.
In normal use, the wheel will generate a quaderature(?) output but

I am looking for a mail-order retailer of high-frequency (3.5MHz)
ferrite rods, size about 10mm x 200mm, preferably in Europe.
Can someone help? Thank you.

I have a UGN-3030T and I need a data sheet.  Web searches have yielded
nothing.

I've been looking around for some PCB headers. I can buy the 0.1" pitch
anywhere, and I use them in turned pin, like this:

but I need some in 0.07" pitch, so I can make a PCB daughterboard that

ever since I was a child, magnets have held a fascination for me. I've been
collecting them ever since. It used to be that you could always scrounge
loudspeakers for Alnico magnets.  Then when the newer ceramic magnets began
to be incorporated into loudspeakers, it became a ...

The attached picture shows IC305 in a Canon camcorder dated about
1993. The IC is cracked and non-functional and it bears the characters
VM at the top and 3D at the bottom. Can anyone identify the component
please.

1. What is the capacity of a ROM ?
2. Except for Read Only and R/W, RAM and ROM are they same ?

Any suggestion welcome how to replace burnt PHB55N03LT on PCChips M754LMR
motherboard.
Philips suggests PHP/PHB/PHD55N03LTA; TrenchMOS (tm) Logic Level FET,  but
no success to find them by 1 piese in Estonia.

Hello people
Does someone here have a datasheet of 8272A IC, used in Floppy Drives?
Googling just gives Linux stuff. I've read that uPD765 is compatible but am
unsure.

Can anyone point me to any webisite or provide me information about
how to build a device that can listen through a concrete wall?
Thanks

I have a fault on my camcorder that is displaying a strange output via the
video out socket on the camera.
When I connect it to the TV, the camera has colour but when the picture is
bright it flickers and the overexposure blurs the real image.  This happens

I have several of these that measure considerably less than their marked
value.  I'm thinking that they might be the type of capacitor that uses
metallized film, which burns off when it has a dielectric failure.  The
