Where can I download this > software (is it free?) and how do I use it? I have win95 and winNT4.0. I have only recently switched over from the good old DOS tools to MPLAB 3.31. I got this version from the 1997 Microchip CD, but you can download MPLAB from the Microchip website as well. I use MPLAB under NT4.0 and it hasn't given me any problems. You just cannot use the emulator (if you have one) under NT. The best part of MPLAB is the simulator. Way better than the DOS version! Niki
