rom41hx - convert a HP-41 rom file to a LIF file of type sdata that can be uploaded to HEPAX RAM with the READROM command
lifutils rom41hx LIFFILENAME INPUTFILE > Output file
lifutils rom41hx LIFFILENAME < Input file > Output file
lifutils rom41hx -?
The HEPAX ROM set can load HP41 ROM images from disk. The file format is a file of type SDATA which stores 4 10 bit HP41 words in 5 bytes of the file. A 4K ROM dump is thus stored in a 5120 byte file. rom41hx generates a LIF data file of type SDATA from a HP41 rom file.
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 HEPAX 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 rom41hx HPILDEV | lifutils lifput lifimage.dat
will put the scrambled rom file with the name HPILDEV into the LIF image file lifimage.dat
