There are no other files named 8080.com in the archive.
071E2.DAT ... 074E2.DAT - data and punch files which are used when
generating the output in the form required by Northboro or
whoever when producing the 4.2 8080 Roms.
DATAIO.BIN - punch file for PROMS (used for testing the results)
PUNCH.TXT - text file which describes the procedure for punching
ROMGEN.* - this is what generates the PNT and DAT files above for
use in generating the Roms. The DOC file documents the
ROMGEN program and its use. The WAY file describes how
to get the 8080 code to its final release.
All of the data on this file (I believe) corresponds to the 4.2 version
of the 8080 Console program.
