The result is HEPAX-1A version which I've included into an archive here.

Thanks, now I have all the four 1A-1D versions :-)

Disc 2
Maybe one of them is the 1C we would love to see, I can't tell on my 71b

I have the 1C version image since more than 20 years :-)
The 1C version was also available in some previous V41 emulator releases, but upon request I can post my 1B and 1C disasm listings here.

Still about versions: the version 0C may be the one that was reviewed by some users/testers in early 1987. One review has been published in HPX V1N3, May/June 1987, and the reviewer (Brian Walsh) wrote "The preliminary version of the EPROM software is missing a significant number of functions scheduled to be in the final modules". Indeed the 0C version is missing the HEPDIRX, HGETA, HGETK, HPOSFL, HREADFL, HSAVEA, HSAVEK, HSAVEP, HWRTFL and PRIVATE functions.
The reviewer was referring to a commercial communication of VM published in the Trading Post Columns of HPX V1N2 p20, that described the HEPAX module. Interesting, several functions mentioned in that document are not in the final production versions: HSAVEMC, HGETMC, ROMNAME and HRESZFL (this one available as user code in the final HEPAX manual).
