Does anyone know where to get datasheets for:
Semefab 05-8728 and KSP 10-124?

Semefab 05-8728 is an 18 pin DIP IC that is connected to the 10 DIP switch
package in a garage door opener.

KSP 10-124 is a TO-92 package (looks like a 3 pin PNP or NPN) in this same
garage door opener.

Thanks -Ira

** The KSP 10 is a UHF, NPN transistor.

The Semefab number is likely a custom uC.

Have you tried asking them ? They may very likely be OEM parts though.

How old is the garage door opener? 8728 is very likely to be a
manufacturers date code. Semefab 051 is probably a custom design.

I don't know when the opener was installed but the garage was built in the
late 70s. The circuit board for the opener says 1999.
