[time-nuts] PICTIC II Programmed 16f688 chips

[Robert Darlington]

Hi guys,

For those of you that are having me pick up the PIC and program it and send
it out,please feel free to go through Ignacio if you want or cancel the
order if you want to program them yourself.  I haven't bought anything yet
so it's definitely not a problem on my end if you'd rather get a programmer
and do it yourself.

If I don't hear anything but Tuesday, I'll go ahead and place the order for
the chips and get em burned.

-Bob
