Stephen,

FWIW, I have a copy of the tnc2118a.bin file and it references KISS. 
Within the file contents are "Last mod:N2WX 03/20/92 Added 1.1.7b 
KISS:WA7GXD 08/30/92"
I can't recall with any certainty if this used a 27256 or 27512 EPROM 
but it occupies the same address space as the MFJ1270B OEM EPROM which 
was a 27256 and contained KISS. The OEM version is tnc2128.bin which 
contains "Last mod:N2WX 03/01/91"

I can send the bin files as attachment in a P mail if you want them.
