Hi, I only join today and I can't make posts yet. I have a solution to your Curve Movement problem.
So you have you want to go from A to C via B, so you want to start at A at time 0, then at B at time 1/2 and finally C at time 1.
So if you make a chart you want it to look like this
T = 0 P = AX1+BX0+CX0
T = 1/2 P = AX0+BX1+CX0
T = 1 P = AX0+BX0+CX1
To get the correct distributions of 0 and 1 you now require three factors, (t), (t-1/2) and (t-1), these factors equal 0 at t=0, t=1/2 and t=1 respectivly. So If you use them like this you get the 0's at the right points.
A*(t-1/2)*(t-1) + B*(t)*(t-1) + C*(t)*(t-1/2)
But this doesn't yet give you the values of 1 where you need them so you need three magic numbers, M1, M2 and M3. You can prove that for this case M1 = M3 = 2 and M2 = 4.
It'll be good practice at least, I did a bunch of practice boards the last few weeks but that's a bit different than actual repair. It's pretty obvious what's going on with those, so it's not very hard to trace the leads, and they aren't designed with faults so
Site is peaking on traffic for the recipes - Sundays are always the big days and we are 200 plus unique visitors an hour right now and it will be like that probably be around 3000 total on the site all day maybe more if Google desires it LOL
Anyway I have a power bench that I don't actually know how to use, but I'm assuming I can take the battery out and power it directly from that to see if any of them turn on.
If you had kids like me that grew up in that era you could just go to your closet and fish out one of the cords from the cord bag. I bet I have everyone of those cord connectors plus some
