rom41er - convert an unscrambled HP-41 rom file to a LIF file that can be used by the Eramco MLDL-OS
lifutils rom41er LIFFILENAME INPUTFILE > Output file
lifutils rom41er LIFFILENAME < Input file > Output file
lifutils rom41er -?
The Eramco MLDL-OS ROM set can load HP41 ROM images from 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. Input is read either from standard input or the file specified by the command line parameter INPUTFILE.
rom41er is a program which generates a LIF file of type X-M41 (E070). The program reads the rom data from standard input or the file specified by the parameter INPUTFILE and writes the LIF file header and the rom data in scrambled Eramco MLDL-OS format to standard output. Note: This program adjusts an incorrect ROM checksum.

If HPILDv1B.ROM is the rom file of the HP-IL development module then
cat HPILDv1B.ROM | lifutils rom41er HPILDEV | lifutils lifput lifimage.dat
will put the scrambled rom file with the name HPILDEV into the LIF image file lifimage.dat
