Here are a series of images taken while taking my PCM apart. This PCM is a GrandPrixStore reprogrammed PCM. You can see the proof of this after opening it up.
The Flash chip has definitely been taken off.
Modem users be warned these images are bretty large (average size=60K).

My question is this. The chip is an Intel AB28F400BX I went to the EMP-20 page and that chip is not listed as being supported. Is it just not listed or is there a different programmer needed?
