[TenTec] CorsairII obsolescence - MCU copying

[mike bryce]

steve and all,

I have the capacity to design, layout and build double sided pcbs

so, don't let that keep you from moving forward. 

I'll be more than happy to lay out the pcb and do the prototypes

If it wasn't for great distances, we would all live a lot closer!
