So slightly annoyed now.. the dualtos boards are missing the 2 inner layers So its going to push back this project again as I can't test the new boards now

EDIT:

I will try and hard wire the missing layers.. The via's are there.. I used copper fill on top layer connected to 0V so hopefully that will be enough to get a board working.

EDIT2:

Now working!

Made a start on the (hopefully) last revision of the booster...

Looking good to me.

C1 is a little wonky though

I charge more for unique items like that

40MHz running on this version.. Worked first time.. so wondering what I did wrong

About the same as C3

Am I seeing things, or does the new dual TOS board only use 8 pins of the HI socket now? In other words just the data lines and GND?

I think the SMT pads are to big for the parts.. that's what happens when you cut corners as use "built in libs"

Not seeing things no.. I've moved the SMT socket there so pins had to go.

PCBs on order, so a waiting game next

I've got 2 more PCBs here, so will order parts next week , see if I can build them up as pre-release boards
