rom41hx - a filter to convert a HP-41 rom file to a LIF file of type sdata that can be uploaded to HEPAX RAM with the READROM command
rom41hx <LIF filename> < Input file > Output file
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 is a filter which generates a LIF data file of type SDATA from a HP41 rom file.
The filter reads the rom data from standard input and writes the LIF file header and the rom data in scrambled HEPAX format to standard output. Note: this filter adjusts an incorrect ROM checksum.
If HPILDv1B.ROM is the rom file of the HP-IL development module then
cat HPILDv1B.ROM | rom41hx HPILDEV | lifput lifimage.dat
will put the scrambled rom file with the name HPILDEV into the LIF image file lifimage.dat
