Funny. I have a 1278 as well, and was using it (in KISS mode) with JNOS back in 1998 when there was a multi-state TCP/IP radio net across the northeast US.

Um, I have an MFJ 1278T TNC, and am running it in KISS mode under 
APRSIS/32.  Stock firmware on it, I believe, though I don't recall what 
version.
