[TenTec] CorsairII obsolescence - MCU copying

[Steve Hunt]

Rick,

You don't actually need any logic between the PIC and the LEDs. The PIC 
can decode the BCD into the 7 segments needed for each LED and refresh 
each LED in sequence; it just has to work a bit harder!

Driving the LEDs should not be a serious problem even if we have to use transistor pull up circuits,  what I saw of th PIC board there should be plenty of room.  The quetion may be, can you get the decoder chips to take the counter output and apply it to the seven segment display.?
