I've put up a schematic Inchworm; on my site of my take on the many fine designs of Microchip ICD2 emulators on the web. It's based mostly on the excellent version by Lothar Stolz. I've used the MAX232 as a voltage tripler to get the ~12.5v needed for VPP and added handy busy & power LEDs.
You will need to program the bootloader .hex file located in the ICD2 directory onto a 16F876 (or 877)

Magic muxing of LED displays...
MIKE
so how do I get to the ICD2 directory to get the .hex file?
Ken
It's on the Microchip web site.
Leon
This directory has 51 .hex files in it.
C:\\Program Files\\Microchip\\MPLAB IDE\\ICD2
Which one ??
That look like your hard drive, not the Microchip web site!
Leon
You have to first install MPLAB (I'm using 7.40)
The load the file BL010101.HEX
It's generally found here on your harddrive. C:\\Program Files\\Microchip\\MPLAB IDE\\ICD2\\BL010101.HEX
You will need a simple programmer to get the bootloader on the first time. PonyProg is one example of a simple RS232 port programmer (the schematics are on the site
PS make sure you do NOT use a 16F876A or 16F877A they require specially modified bootloaders.
hi William, thank you.
