Re: [emax] Display not working

2012-12-03 by Ted Summers

I will check that pin 2 when I get home....

I have no white displays left.
I have 5 yellow which were not paid for and no response from the people who
reserved them.
Was about to start going down the waitlist.

Will update you in a couple of hours if this appears to be a fuse.

Thx,
Ted
