Dead LVB tracker board. Good ADC AZ and EL. Took a lightening strike. Shot the bug down to the serial port. No output. Is it the uC or the line driver?

I'll include a direct cross for the latter. Lucky recipient will have the pleasure of crossing his or her fingers and powering up.

Any 16x2 44870 compatible display will work.

NO LCD, CASE OR BUTTONS. These had a higher calling.

PS: I'll include the never working difficult to find AMSAT official USB port. Great conversation piece.
