Default Re: I found it! A very sorry looking MK14.

The circuit diagram shows 3 decoupling caps, C3,C4,C5, on the output from the 7805, bottom left of dwg.

The board layout diagram only shows C3 & C4, and those are the only ones on Micky.

How did these boards work so well with only two decoupling caps ?

Regarding drilled-out vias, I'm certain I never drilled any holes, but I'm still checking. It's much easier to do this before I fit the sockets.

Cheers,
