HP49 ROM update specifics???



#3

Does anybody know if a list of specific upgrades/improvements/changes exists for each of the operating system upgrades available for the '49G? If so, where might I find such an animal???

While upgrading is always a good thing, I'd like to know what I'm getting before I install it! Specifically, what deficiencies were noted in the earlier loads and how were they corrected in subsequent loads?

In advance - thanks!!!

~Bryan


#4

Hello Bryan,

I found these notes from the ROM 1.18, i.e.
it is a text that comes together with the ROM 1.18.
It seems to be the only source of information.

I also wrote a mail to some mail lists.
Lets hope to see if someone can help.

Below the text form the ROM 1.18 notes


Sincerely,

CMarangon


==================BEGIN OF THE TEXT=========================
HP 49G ROM 1.18 Release Notes

What's new from Release 1.16:

Holding [BackSpace] during Boot Sequence will put the calculator in
safe mode. User libraries will be completely ignored unlike previous
version. STARTUP will also be ignored if [BackSpace] is held after
the MetaKernel logo appearance.

Switch between complex to real mode from the keyboard (press and
hold down LeftShift and then [TOOL]).

Decompiler now fully compatible with HP48 (DECOMP$).

Kermit in ASCII mode handles \"

EQW allows input from the constants menu

EQW returns valid object for oo (infinity) and ? (NaN)

Filer doesn't crash when launching library commands < #140

Program << "" "" INPUT >> doesn't crash when launched from the Filer

MASD allows expression GOSBVL =label

MASD allows in sysRPL $ "string"

CAS correctly handles ATAN(X) with the INTVX command

PLOT(X) LeftShift F6 LeftShift F5 ENTER fixed in algebraic mode

Numerous bug fixes


What's new from Release 1.10:

PORT1 memory management changed to fix problems with library in port 1.

HP48 MES (Multiple Equation Solver) is now integrated and available
through menu 116 (same as HP48).

SysRPL decompiler is now integrated using the ->S2 command. ASM and
ER are now available in library 256; you no longer need to attach
library 257. System RPL stack is available if you set the flag -85.

All functions related to SysRPL require that you first install the
entry points library (a new version is inlcuded with the ZIP file)

STO has been modified to work with low batteries and the flash --
the function is now slower because of temporary storage.

SIZE returns the number of digits for an integer instead of 1.

Symbolic series: SUM(I=1,N,I) will return (N^2+N)/2. Implementation of
gamma, digammas etc. functions.

New Y= window: You can now create your own user functions and combine
functions together like Y2(X)=Y1(SIN(X)).

Switch between approximate and exact mode from the keyboard (press and
hold down [RightShift] and then press [ENTER[).

New power algorithm: 3^1000 takes less than 2 second now.

User RPL optimization: 1 1000 FOR I NEXT is now much faster. Binary
functions related to integers are also faster (+,-,*,/,^,NEG, INV, SQ).

STARTED and EXITED can customize the command line editor.

Complex matrices are now displayed in textbook mode.

It's now possible to transfer the ROM of an HP49G to another one using
the ROMUPLOAD command. You can also control another HP49G using the
Xmodem protocol with a new Xmodem server, XSERV:
Put the calculator in Xmodem server mode
No Inputs/outputs

The Xmodem server recognizes the following commands:

P: Put a file in the calculator
G: Get a file from the calculator
E: Execute the command line
M: Get the calculator memory
L: List the files in the current directory

XGET: Get a file from a XModem server
Input: the name of the file to get (a global or local name)

XPUT: Put a file in a XModem server
Input: The name of the file to send (a global or local name)

ROMUPLOAD: Put the calculator in ROM upload mode.
When in ROMUPLOAD mode, the calculator acts like the FDP program,
allowing another calculator to upgrade its ROM.
(The speed must be 9600 bps for a ROM upgrade)

MASD is in the ROM; attach the library 257 to use it. You will also need
the extable library in order to use the mnemonic tables. The SystemRPL
stack is not finished.

Numerous bug fixes
