I begin a resource page about this chip
(programmable melody generator chip by General Instruments)

Anybody that would have info about this chip especially

I'm looking for the MC141544 datasheet.
This is video chip to generate menus in an LCD display.
No trace of this component on the web and no trace on the Motorola site ...
Many thanks in advance

HI I am in the process of fixing a car amp.
These transistors are clean blown off ! I don't know how it happened
'cause it arrive to me in this shape.
Anyways I have these transistor packages to replace :

Does anyone have the electrical specifications for an SD5101 quad FET,
which is packaged in a 14-pin DIP?  Nine of these are used on the DEC
M8018 writable control store module for an LSI-11, to interface between
the MOS-level microinstruction bus and the TTL-level logic and memory ...

Are there any cheap IC's around, to do the simple calculator operations (add,
subtract, multiply, divide, square root)? Or is a microcontroller better to do
this?
thanks!

Got a surface-mount IC that I can't spot anything for on Google. Need to
ID it so I can try to chase down the problem in the circuit it's in.
It's a 14 pin, surface-mount DIP. No obvious pin 1 mark (no notch, dot,
or circle), but I'm assuming that, as is conventional, lower left ...

Does anyone know of an IC which has a mic pre-amp and an automatic gain
control circuit?  The best IC I've found is the SSM2165 from Analog Devices.
Do you know of any others I should be looking at?
Many thanks in advance,

I have a 2-3 year old Olympus D-460 Zoom.  It's worked great up to
now.
Recently it's developed a problem where the images are degraded.
Every image has the same problem:

I blew out a 1 mfd 120v.a/c cap. in my OLD generator automatic switch and
can't find a replacement. I was wondering  what I can use for a substitute?
The original is a can about 7/8"D. X 1-1/2" long, wound tinfoil
inside(was):-) and a lead out each end. Would a 1 mfd. 400v.d/c work? ...

I have a one-board, transistorized AM receiver that is inop.  Two of its
three I.F. transformers were torn off and are lost.  I want to get
replacements for them.  Unfortunately the manufacturer of this receiver
is long out of business so replacement parts are not available.

I'm looking for a small handful of ICS501 (http://www.icst.com/) clock
multiplier chips to complete a couple of "Montreal Fox" boards
(http://www.qsl.net/ve2emm/pic-projects/mfox/mfx501-e.html) for a friend.
Before I try to fast-talk a distributor or the manufacturer out of some

Hi'

Anybody know of a chip which permanently keeps track of month/day/year
without allowing a user to set it?  
What I mean is something that is already preprogrammed, has its own
little battery built in, returns the current date when asked, and will

I've used a few local fabricators to do some aluminum chassis for me in the
past but was wondering if there are any really big names that do business
like some of the big PCB houses.
For example, I have alot of boards done at PCB express and it's great the
