wp34s crystal kits -- don't worry

[David Griffith]

For those of you who requested crystal and cap kits from me for your wp34s calculators, don't worry. I have your requests. I'm waiting for crystals to arrive from China and it seems like they're taking their dear sweet time about it.

Hey David!

I'm not thinking of a complete board swap, just an add-on board with a few components. Walter has already explained that we will not be able to add a substantially better display without an embedded controller which would demand a larger battery which ...
