From: News on 13 Aug 2006 23:04 I have been following the newsgroup for some time now and am waiting for the HP50 to arrive in OZ. I am a bit confused though with the ROM version numbering. HP say v92 other people say 2.09. How do I know which is which and what the differences are? -- Dan Field (Surveyor)

V92 is the version of the internal emulator OS, which runs on ARM processor, which in turn emulates the former calc "Saturn" processor. 2.09 is the version of the Saturn-level OS (this continues the version numbering of the original HP49G series, which had only a real Saturn CPU). When you type VERSION you see the Saturn OS version. When you press ON+D you see the ARM OS version (if you have trouble exiting then press ON+C) Each ROM update file simultaneously reloads both the ARM OS and the Saturn OS code; if your calc comes with 2.08, it will be worth updating to fix a couple of things (e.g. LINSOLVE).

From: John H Meyers on 14 Aug 2006 00:47 Continuing... There's even a third separate component to the whole ROM, which has yet another version ID of its own: Type VER to see the CAS version number (and date). So the entire ROM file actually contains: o ARM OS (by Chinese manufacturer Kinpo?): ON+D: 92 o Saturn OS (HP's RPL etc.): VERSION: 2.09 o CAS (by Parisse, Heiskanen & Fiechter): VER: ?.?????? Plus various Easter Eggs, Tetris, etc. :) [r->] [OFF]

Oh, I forgot that there are also now two additional libraries which implement the newly restored "Equation Library" (EQLIB command); these libraries now come separately, and may be stored into user flash (port 2). There was recently a little problem for those who are updating older 49G+ ROM, because the new ROM flash file updates only the ARM/Saturn/CAS permanent ROM, and had omitted the necessary final Equation Library files (to be separately stored into port 2); the missing libraries are supposed to be added by HP to the downloadable ROM update, so that 49G+ users can complete their update (the 50G should already have been sold with these in place, and should have had no problem with EQLIB after updating ROM).
