untill then we all sure dont know when the professed gaint will be
out yet ...
has not shown up yet,why this has not happen, what do "I say " hp is
the best calc . Okay this is kinda tricky here (sharkperic lang) one
questions and one comment don get confuse.
This loooooong awited calculator has not show up yet at my door steep
save money , cann't save anymore perhap it is ot going to happen ever
Qnos
Probably because it is the last, best calculator ever put out by HP. I
wouldn't sell or trade mine for anything. It is a classic.

I have 2 HP49G+ and a 48GX with a mechanical engineering card. Tempting
to get rid of it but I know I'll be kicking myself as soon as its gone.

Cuz it's old and WAS excelent on that time. collector items are usually expensive
As it's been stated many times here, the magority of buyers (HP48) buy it to
use it rather than for collections. I guess all collectors have enough of
then already :)
Reliable, stylish, powerfull mashine, real working horse.
Cheers

What I don't understand is why there are no modern equivalents to classics
like the 42S, 15C, 16C and the 48GX. People are beating themselves to
death paying $200 and more for these calculators on Ebay - someone could
easily go to school on these designs and build themselves a nice niche
business. Instead we get foul tips like the 49G+ . Nice try but how about
a real keyboard, and native code instead of emulation?
Criminy, they make the 12C still. Why not some others. Jeez.
You are free to program native ARM CPU applications using HPgcc
Then your 49g+ will really fly

In actuality, the original source code for the HP41 is available in
hard copy form for anyone to type in. Check Warren Furlow's
http://www.hp41.org site and enter "source code" into the search tool.
Select "VASM Assembly Listing" and you will see a page-by-page listing
of the original HP41 source, obtained by Richard Nelson in the early
1980's from HP Corvallis. He got it with permission and made copies
available to anyone who wanted it, provided that they agreed not to
contact HP with questions. Since several disassemblers were devised in
the HP41 days, I wouldn't be surprised if the ROM code of the 42S could
be disassembled as well.

I typed it all in a few years back. It was a great way to learn a lot
about the inner workings of the HP-41.
I need an assembler to verify it against the actual object code. The
assembler that I wrote for the Classic and Woodstock series instruction
sets can't easily be extended to handle the Nut processor because HP
used some mnemonics as labels too.

The HP-42S uses a Saturn processor, so the ROM is written in RPL and/or
Saturn assembly. An HP-41 disassembler won't help much with that, but
there are plenty of Saturn disassemblers around.

hmm, emu42s have simple disassembler inside - but not to make list
to file or intelligent lables etc. like advanced disassembler...
