If one of the thousand and one PIC chips wouldn't do, there are perhaps
100 makers of microcontroller chips each with hundreds of products with
a wide variation on capabilities. I suspect Tentec can't see the profit
in the time taken to make the new board and convert the program IF they
even still have the source code for conversion.
I fear the quantities needed today are a few a year and that won't pay
for a year of reverse engineering to make a working board, but it would
be an interesting project. It would work best starting with an Omni VI
with a working control board.
A missing simpler IC could be replaced by some sort of FPGA almost no
matter how complex, indeed there is CPU logic cores for the larger FPGA.
But its so much simpler with the original source code.
NP4Y did it to enhance the Omni V but likely the Omni VI is a lot more
complex, for sure the + with lots of DSP on the same controller board.
