Anybody who has experience with interfacing the M100 to input and output devices or who knows of available text about this subject I would be interested in learning about these things. I am referring to using the M100 as a controller to monitor inputs from limit switches,thermostats, etc. and then use that data to control output signals for motors,lights etc. I especially need info on how to read the proper ports. I am sure the RS232 and cassette ports can be adapted for such things as this. PLEASE HELP IF YOU CAN!

Your best bet on information on interfacing the Model 100 is the Service Manual (R/S Catalog Number 26-3801/3802). The easiest ports to use are: Cassette Relay (Use BASIC "MOTOR ON" AND "MOTOR OFF" to turn it on and off) BAR CODE Port – For controling serial devices RS-232 Port – For serial devices Sears, Tandy, and BSR sell controllers that allow individual AC devices or Lamps to be turned on and off; although this system can NOT tell if a given device is on or off. I use this for a sort of burglar discourager (it shuts my lights on and off randomly at night when I am not home). Computer controllers are available to interface with computers. Let me know if you need more information.
