Quick update: got the new PIC version of the boards back from the PCB printing service (REV E), and quickly soldered one up,
loaded the PIC firmware, and it works! Tested with a couple of 1A2 phones (2564's). Here's a pic:

I could probably build 10 or so of these, perhaps at the rate of one per week. Kills half a day soldering it up and testing.

Anyway, for those interested in this board, I'll try to make them available somehow.

But would love first to have one of the tech guys who admin sundance-comm to test one out, just to see if there's anything I should
know about or add. If there's any takers, let thyself be known, and I'll contact you via PM/email and send you one no charge.
All I ask is you foot the approx $25 USPS bill for shipping it back to me after a few weeks/months of testing.
