Who owns the HP-49G firmware?

[Steve Meserve]

I'm new to the 49, but I've been reading a lot about it's history. I
know that HP shut down it's calculator development division, and that
1.18 was the last official firmware. I've upgraded to 1.19-6, and so
far it looks great. I'm wondering who now "owns" the 49 firmware code?
Is this the original code base from HP (1.18), or is it a complete
rewrite? Are the original 49 developers still out there (hpcalc.org,
et al) moving the software forward? Thanks in advance,

Steve

It's a bit of both.
The HP49 firmware is own by HP and license some part of it (without owning
it) like :
The CAS (some is own by Bernard Parisse, and the rest by Mika Heiskanen and
Claude-Nicolas Fechter)
The MetaKernel is own by myself, Gerald Squelart, Cyrille de Brebisson and
Christian Bourgeois

And what about the rest of the 'intellectual' guts of the machine? The
ROM and micro-code which does the unit conversions, the
multiplication/stack handling etc...?

Just curious...and wondering whether there is sufficient material
available that a HP-48 could be emulated under Linux on an Ipaq...?
