HP40G ROM version
Axel Bodemann
I would like to buy the HP40G.
1) Concerning the CAS, does anybody know what ROM version of the HP49G
is comparabale (or even identical) to that of the HP40G?
2) Is there a way to check the HP40G ROM version on a real calculator
by any key combinations so that I can check it on the store?
Thanks for any help,
Axel.

I can't help with the first question but you can find out the ROM
version on any 38G, 39G or 40G by typing VERSION in the HOME view. In
the case of the 40G there was only ever one version: "HP39-A".

As far as I know, CAS in ROM 1.19-1 is almost the same than CAS in
hp40g calc. You can execute VER command on CAS (EQW) in hp40g and get
this:
HP40 CAS by Parisse,
Heiskanen and Fietcher
4.2000427
So it is version 4 of Erable and 'was done' 24th April. Anyway, sure
someone could correct me if I am wrong.

VERSION command will tell you:
Version HP39-A
Copyright HP,
1993,2000
The sad news is that hp40g is not FlashROM, so you can't update. Only
some pre-production models have FlashROM :(

Just a few remarks, as Colin and Manrique already replied.

Why not the HP39G? I got mine from Samson Cables, but it can be purchased in
Europe too: http://www.dynatech-bes.de (under "ohne CAS")

According to Jean-Yves Avenard, 1.19-1:

(For reference: 1.18 -> 4.2000031, 1.19-6 -> 4.20010912)

VERSION should suffice, but in order to know the complete version number of an
HP39G or an HP40G type in: LIBEVAL 171;58 It will probably return the strings:
"Version HP39-A1.40" and "Copyright HP, 1993,2000". Likewise, _on the HP38G_
LIBEVAL 171;0 outputs: "Version HP38-A1.67" and "Copyright HP, 1993,95".
Aside from the unreleased HP38G+ and some HP39/40 prototype units (VPN reports
that his ROM version 1.32 has a label on the back that says: "Press F2 at boot
to switch between 39G and 40G. Then press ON+F3."), the HP38/39/40 are single
version machines: a Sys-RPL programmer's dream! :)

But the HP49's architecture has been retained: there are flash pages, flash
pointers, and also the FLASHEVAL command.

Although the 40G has no flash ROM I hope it is worth the money (EU 60
compared to the 49G: EU 149!). I don't mind much programming on that
calculator - for the big stuff there is the PC, for the lab at work I
use my nifty little 32sii). Just interested in a calc with CAS to play
with, e.g. at long railrod trips :-).
Best regards
Axel.

So from the users side, it's an algebraic-only machine.
