Hi,
I have 2 Falcons apart down to the motherboards, One for experiments
and the other one has a problem that I'm trying to fix.
Both have similar looking NVRAM chips, 2nd set of numbers are the same
but top number is different and numbers on top left corner are different.
I've took a snap pic of each, I'm going to try e-mailing them to you.
Pass them around to anyone, who knows something about these.
Just don't post them anywhere without asking me please.
I consider my snap pics, as part of my work.
Anyone who uses a Falcon or does work on chips like this and
wants to see the pics, just e-mail me and I'll e-mail them to you.
thanks,
Barry
