I run KISS only EPROM's in 4 MFJ1270B's on my Linux system. I found the 
KISS only EPROM offered two advantages over a Native Mode EPROM that 
contained KISS.

1. The TNC never comes out of KISS mode unexpectedly.
2. The KISS only EPROM solved many strange timing problems that the 
Native Mode EPROM exhibited when in KISS mode. Things like transmitting 
over incoming data, not transmitting data that the computer sent to the 
TNC, etc, all went away when the KISS only EPROM was used.
