Re: LL PCB repair

Yeah I use those low profile ones too.

This is all I have on LL notes for Rom/Prom and Ram checks

Rev1

Program Ram Region
0000-01FF
Vector Ram Region
4000-47FF

This is pretty much what I do for all of them, just list the revs with the
fluke sigs, and Ram regions for quick testing. I've not gotten around to
actually writing scripts yet.
