Thank you for your reply.
No, unfortunately I do not have an HP-IL/PC card. (Or a computer that could use it; I remember that an old 4.77 MHz IBM or clone was needed.) I do have an HP-9114B, and I thought there was a utility (LIF to DOS?) to convert a file for use in the HP-IL drive from a PC.
No, I have no EPROM box, just the ZEPROMS and burner, HEPAX, and ERAMCO Rambox.
I really don't think I need the OS files (yet), since the battery is still good in the Rambox, and the OS is still there from the last time I replaced it. I've either still got the original copy I made, or I could make another, I would only need to figure out the commands again to archive a ROM to storage, using one of the devices that I already have. From my memory 10 years ago, I thought the challenge may have been getting the ERAMCO set up to write the OS to the upper 8K of each 32K bank, since those blocks were normally protected from overwriting so the OS would not be overwritten. Or perhaps the protection existed only in the RSU software? That's something I cannot remember....
Concerning the Clonix, where do I find out what that is? Is it essentially the same functionality as an ERAMCO Rambox? I never heard of a 128K Rambox, is that 32K bank-switched 4 ways?
And a last curiosity, where there different versions of the RSU software? I think mine says 1A and 2A during Cat 2. If there were any updates, it would seem best to use those.
