Ta-da...

To allow for a full sized crystal and keeping single sided I shifted the
reset switch to under the ICSP header, so it now has to be SMD now. :-)

Still not convinced of the benefit of the DS1233 on a modern PIC though.
And if someone really wanted to they could stick it across RA5/MCLR in a
to92 package on the host board.

I'm picking in a lot of applications this type of 'stampalike' will not
even have MCLR enabled to allow use of RA5 anyway.

Anyone got a good argument for an external reset manager on a micro that
has a good brown-out reset anyway?

Cheers, Me.

 I could squeeze one in on there I think, without too much of a
reshuffle,
