I'm easy time wise but I did enjoy a slightly more casual weekend time. If I
cycle then I'm pretty unresponsive until about 1pm so a Sat afternoon would be
good. If you'd still like a Thursday talk we could do that and do a bit more
hands on with some parts etc on the weekend. Fine either way; I was being
facetious and a bit rib pokey at Frames' formality ;-P

Ok. Given "an example is worth a thousand instruction manuals" having a design
problem to think through and then prototype would be useful I think.

I've pondered showing how a wirewrap works will take all of 15 seconds plus a
minute to practice a few wraps so why is probably a better question than how.

I have a few things on the go atm and I will bring one along more to talk
about the steps along the way. In some cases you may not have a firm design or
you may need to shuffle some microcontroller or CPLD I/O functions as you
discover things along the way. Swapping things around is fine and reasonably
easy if changes don't move towards smoke and hot wires. Good for learning and
all possible with wire-wrap. Alwyn found a useful NASA reference for wrapping
and it has some reminders about how to lay out the wraps.

How about setting up for either Thursday 12th April and/or the Saturday a few
days later ?
