It has been built several times and works perfectly with MPLAB

How do people not find these FAQs?

If you hit piclist.com and search for "BUILD AND ICD" you get right to it.

Subject: [PIC]: In Circuit Debugger?


Have any of you had success building your own ICD for the Pic16F87x that
works with MPLAB (or even one that doesn't)?

I've been poking around a bit, and I am no closer now than when I started -
and a lot less enthusiastic.

There is some info contained in the piclist archive, but nothing that shows
a successful attempt at it, mostly bits and pieces or quotes from elsewhere.

I did find the d877.hex disassembly - thank you very much:
http://www.piclist.com/techref/microchip/16f877/xicd.htm

And the MPLAB-ICD Module Schematics:
http://www.microchip.com/Download/Tools/PICmicro/ICDS/MPLABICD/etn21d.pdf

Problem is that Pic16lf876 (U1) is not the target for development, it is a
controller/interface acting as a go-between with the PC and the target
device: Therefore, to make a device that worked with MPLAB, we need to know
the contents of U1. I haven't bothered Microchip yet, I doubt they'd be
sympathetic.

The early bits and pieces I found seemed to imply that this was a reasonable
project. But it now appears much more reasonable to simply purchase
Microchips package.

Wondering what your experiences have been like.
Bruce.
