I've had X10 since the middle 1980's, started with DOS software and the TM109 serial interface, graduated to the CM11A serial interface and Active Home, that worked fine until XP didn't like my motherboard and the serial port started to vanish and reappear at odd intervals, so in 2005 went to the CM15A USB interface and Active Home Professional software. I have modules with almost every name on them, both lamp and appliance modules and every one of them is still happily working.
