My K107 Serial LCD Controller board and kit has undergone some  
changes in this new release. K107 Board version 2 has some  
functionality added specifically for PICAXE users but that benefits  
the DIYers. The PICLIst was the single largest source of sales of  
bare  k107 boards sold so I am writing this to let you all know about  
it.

K107 Rev One was designed around the Anderson 106/107/117 serial LCD  
controller chips. It used a 16F628/16F648 with its internal  
oscillator. Professor Anderson also had a 108/118 chip that was  
designed to run at 2400 baud for the PICAXE and had a 4 MHz resonator  
on PIC pins 15/16 and shifted the connection from LCD pins 4/6 from  
PIC pins 15/16  to PIC pins 12/13. Russ and I redesigned the K107 to  
add holes for the resonator in 15/16 and with some solder pads and  
fine traces so that you could slice the PIC 15/16 connection to LCD  
4/6 and then place two solder bridges on the pads and connect 12/13  
to 4/6.

  While we were  at it we added some plated through vias to allow  
access some of the unused pins by hand wiring/soldering that were not  
accessible in Rev 1. We also moved the "Test Mode" jumper pins (J6)  
into line with the input pins (J1) so that should a DIYer wish access  
to both TX and RX of the PIC USART (pins 7 and 8) he would put a 4  
pin connector in place of j1 and leave J6 out altogether.

So, the K107 not only has added the ability to use Anderson's 108/118  
chip we have made it possible for a DIYer to use a resonator in his  
own design. I had quite a number of requests for bulk quantity bare  
boards so I added a bundle of 10 boards at what I think you will find  
is a very good price.

I get quite a number of orders from beyond North America. I recently  
got a note from Howard Winter in England, recounting his dealings  
with customs and the VAT and the vagaries of how and when it is  
applied. At his suggestion, I posted it to my Tech Blog (K107) at
