NAME
rom41 - a filter to unscramble an Eramco ROM image
SYNOPSIS
rom41 < rom_file > output_file
DESCRIPTION
The Eramco MLDL-OS ROM set can save HP41 ROM images to disk,
and the file format used has become a de facto standard for
such images. It stores 4 10 bit HP41 words in 5 bytes of the
file. A 4K ROM dump is thus stored in a 5120 byte file.
rom41 unscrambles such an image, storing each HP41 10 bit
word in 2 bytes of the output file, and therefore a 4K image
takes up 8192 bytes when unscrambled. The resulting output
file, although larger, is easier to process with other
programs.
EXAMPLES
If myrom.rom is an HP41 rom image, produced by the Eramco
MLDL-OS and stored in a linux file, then
rom41 < myrom.rom > myrom.out
will unscramble the image and store the result in myrom.out
