-Sure. The 8741 is a member of the 8048 family. The '7' in the part
-number indicates an EPROM instead of mask ROM.

Sounds like "8741" is a date code.  I know of no X-10 modules that use
the Intel 8741 for anything.  The chips that are used in most modules
are custom GI parts.  The only microprocessor used in their controllers
(that I know about) is an NEC 80C48.
