History of PLC

[GaryS]

I was going through some old files last night and found this
I thought I would pass it along to those who may be interested
I have no idea where it cam from or even when I downloaded it
it is just interesting
Sometimes I download thing just to save them

And sometimes you forget to attach files

 

[GaryS]

I can assure you I did send both times
I guess they just don't e that file or it's to big just over 1m
it is an interesting read if I could get it out there for you
