HP-IL checksums or not

Who knows for certain of other non-HP modules. It would be quite a pain for your user if you were to tag the transfer of such a module as faulty.

The LIFUTILS programs "rom41hx", "rom41er" and "rom41lif" recompute the checksum of the input rom image. If you prepare a rom image as HEPAX-SDATA, ERAMCO-MLDL OS or uncompressed SDATA file in this way you should not worry about missing or wrong rom checksums.

The HEPAX "readrom" command complains checksum errors but stores the rom image into the destination page anyway.
