bin2hex
  Converts binary files into an Intel Hex or Motorola S-Record file.

hex2bin
  Converts an Intel Hex or Motorola S-Record file into a binary file.

splitHex
  Splits an Intel Hex file into two Intel hex files - one with the 
  even bytes, one with the odd bytes.

moveHex
  Changes the address bytes (and checksum) in each line of an Intel Hex
  or Motorola S-Record file to a different address. The first hex or
  S-record line in the file should contains the base (lowest) address
  in the file.

hex2Ent
  Converts an Intel Hex file into an ENT file for the Sol-20. Can also
  be used to remove the LF from an existing ENT file so the file can
  be loaded at 9600 baud (with 100ms delay at end of line) instead
  of 1200 baud.

These are simple command line utilities designed specifically for manipulating
files from the 8-bit days of early computing. In this light, only 16 bit
addresses and a 64K address space are supported. This, in turn, keeps the
command line options very simple.

The .exe files here are Windows compatible - including 64 bit versions of
Windows. The source files should compile and run under most any operating
system.
