Hello,

     We are trying to identify an electromechanical relay on a PC board we
bought from OR Industrial Computers in Germany.  The markings on the case are:
SDS DR5V.  (The SDS looks like a logo). According to OR, it is rated to 160
volts AC and 3 amperes.  We would very much like to get a data sheet from the
original company.  The U.S. sales rep. said the relays may be from
Switzerland!  Any ideas?  

Thank you,

I’m looking for a small switch for a low voltage circuit. Ideally the
switch, after turning on, will be a potentiometer or digitally scaling
device that will offer a variable resistance to control a circuit. Please
e-mail replies to dm3…@aol.com or if a manufacture you can mail or call:
Also, I need prices in quantities of 10,000, 50,000, 100,000, and 250,000.

I want to know 54C464.

I can’t find it in data sheet.

IC is written 9410 V53C464AJ8C.
9410 maybe Lot. No. …

If you know 53C464, say me please…

I’m looking for a schematic for a simple, proven micro controller
design based on the x86 processor (8088, 8086 or 80286 prefered) and a
few discrete components (RAM, ROM, etc).

I just need the basics: cpu, RAM (64k is fine), ROM (64k is also fine)
and UART.

I would greatly appreciate any help pointing me in the right
direction.

Thanks!

Please help me find a manufacutre of project motors. I can not design my
circit until I have a motor that :
3V DC
high torque 31 oz/inch stall

 Low priced.

Your help would be appreciated. Please email me direct if you have a
lead.  My searchs have turned up nothing so far.

Hello!
newbie here – please forgive any of my failings of netiquette…

I am desperately seeking information on the Intel/Signetics 8049
microcontroller.  I was recently given the assignment of obtaining
documentation and generating code for a system designed around this
chip.

I am looking for sources for a cross compiler/disassembler/development
system for a PC and/or a method that will allow me to read the code
out of an existing processor with the security bit set.

Inherited this nightmare from the previous engineer who left no
documentation or source code.

I am aware that this processor is no longer being manufactured, a
redesign is in progress based on a more current processor.  This is a
band aid to keep things running until the new design is complete.

Any help is appreciated.  Thanks in advance.  Reply here or by email.

I recently aquired a mac II.  Worked fine untill I plugged in a modem that uses ADB for 5volt supply.  I
cut the ADB connector from the modem and was using it with a mac plus, and got power from
seperate power supply.  When I got the mac II I reconnected the ADB jack incorrectly and when I
started up the computer the mouse and keyboard didn’t work.  The computer still displays and
seems to be fine with the exception of the mouse and keyboard.  I was told that there was not any
hope and the whole board was wasted.  Is there only one faulty component , an ADB chip that I can
replace the damaged one with

I was rummaging through some of Steve Ciarcia’s old Circuit Cellar
Articles and stumbled onto the Audio-Video Multiplexer that uses this
chip. I haven’t had much luck in finding one, if they’re still even being
made. Any guidance would be appreciated. Thanks in advance!
