[time-nuts] Possible STEL-1173 replacement

Apparently the PLCC version of the chip is a lot easier to find than the DIP chip.   One could make an adapter board to use the PLCC in a DIP socket.   The PLCC will probably not fit between the rows of legs of the DIP, so the adapter would need to be bigger than the DIP footprint.  Or if vertical space is available use a dual board approach where the PLCC is mounted to a vertical board on a DIP carrier board.  I don't have a FTS-4040 to check what the adapter configuration would need to be.

Haha! That one again. Would be nice to cook up a FPGA replacement for 
it. Should not be too hard, getting the pins match is what will hurt.
