Are these TNC-2 clone devices?

If so, make a "double-decker" ROM in a 27512 instead of a '256.   Put your KISS 
code in one half and a standard TNC-2 TAPR 1.1.8 or 1.1.9 code with the cal 
routine in the other half.   Grounding or +5VDC on pin 1 of the standard eprom 
will select between the two halves of a 27512.
