jnos110k.zip is the source code for JNOS release 1.10K. If you have the source code already, for version 1.10j, then obtain: upd110k.zip, which contains all changes made between 1.10j and 1.10k. jnos110k.exe is a compilation for an 8086 cpu, based on distconf.h. It is intended for evaluation use; you will probably want to edit distconf.h to select only what modules you need, save the result as config.h, and then compile for the desired CPU. cmdshlp4.zip is a complete collection of online help files for Jnos 1.10K. 73, de James Dugal, N5KNX jpd@usl.edu
