Doug: Depends on what you mean by "better". If you mean "does it properly emulate the PICs' operation", "does it support EVERY SINGLE PIC that Microchip makes", "does Microchip promptly fix whatever minor bugs DO creep in", or "does it allow source-level debugging of code written for Microchip's MPASM assembler", or even "was it written by a chick", the answer is YES. If you mean, "does it have a user-friendly interface", the answer is NO, NOT YET. By April, 1996, though, Microchip's simulator will be fully integrated into MPLAB, the new interface for Microchip's Windows-based PIC-MASTER emulator. -Andy -- Andrew Warren - fastfwd@ix.netcom.com Fast Forward Engineering, Vista, California
