Dallas semiconductor makes a similar device called a SmartWatch and I know that its timing is completely independent of the host. I'm sure that the SMT version is independed as well because: It will work in an IBM PC as well as an Apple. PC's run at a wide variety of CPU clock speeds. It plugs into a standard ROM socket with no other connections. The system clock or CPU clock isn't available at the ROM socket in an Apple or a PC. ___________ / Tom Metro \_____________________________________________________________ | _ _ | | INET: tmetro@pro-angmar.uucp --/\/\_| |_| '- DigiTell, Inc. | | ARPA: crash!pnet01!pro-angmar!tmetro@nosc.mil Newton, MA | |_UUCP:_[ihnp4 sdcsvax nosc]!crash!pnet01!pro%angmar!tmetro________________|
