Have PM'd since that should trigger an email notification.
I would say please bring one along anyway but I'm loathe to ask unnecessarily as there's nothing worse than having to bring a bunch of stuff with you!
For the record, the talk I will be doing is "PCB Repair 101". It will mostly be free-form, otherwise known as winging it but I am putting some slides together so that it has some form or structure. A white board will almost certainly be a must as well.
I can then follow this up with shorter demos on various bits of kit if this is of interest but that will absolutely be off the cuff.
I am trying to find the time to put together something on Vectrex coding using modern tools, aka known as how to get stuff done in the quickest possible terms without getting bogged down with 6809 assembler. I would make no reservations though about the fact that most of that will be snore worthy unless you know programming, preferably C and some of the concepts of at least what a vector is!
If there's no interest on that then I can skip it...
