PICE-51 In-Circuit Emulator

This emulator model is intended to supports a few obsolete micro: NXP / Philips P89C66x, 87C552/554 and Dallas Semi DS80C320/520/530 microcontrollers only. All other 8051 MCU are supported by the Phyton PICE-52 in-circuit emulator.

The image above displays an assembled PICE-51 emulator. This is a palm-size header comprised of three stackable boards: a Main Board, POD, and Adapter (from top to bottom). The Trace Cable allows to trace external signals and output triggers.
