I only have a very small number of SKU202 units left, but SKU200 (being built
sometime in the next few weeks) will have better tooling for the grid keyboard,
and I can probably get you a couple.
We hope that the final tooling (which includes screws to ensure the grid doesn't
warp up over the keys) feels better than the C1 samples.

Martin will have to confirm that name.  Our internal name has been "option C",
but that has to change.

Those units had been used in S/R testing in Cambridge, so they
were probably wrong on Friday as well.

0402, but you are just shorting them, not placing a component.
In order to fix the "first keypress during suspend lost" problem,
you need to short out R351 through R354.   These are located
right next to the keyboard connector.
