datasheets for Semefab 051-8728 and KSP 10-124

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 Semefab number is likely a custom uC.

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.
