I changed it just to be sure, but that's not it. The problem is that the incoming data stream, after being converted from current loop to TTL voltage swings is not clean enough to drive the 7404 inverter properly. For all I know it may be a problem with the current loop/RS232 adapter I'm using to drive the board.
Did you verify that you can drive your asr33 with your adapter correctly? If so, then switching the 2SIO port to RS232 should get you up and running.
