As I remember, there were not that many parts on Doug McKinney's board, a
MAX2323 and 74HC04.
Bet you breakfast you blew out the MAX232 ... connecting/disconnecting
serial connection when powered up.
The early Maxim parts were not ESD protected ...newer versions of the IC
are.

I find this problem is HALF of the TNCs/Modems that are reported Dead.
The other Half have the serial connection directly connected to serial port
on the CPU (replace CPU).
