Help on 42S ROM - Help Luiz! - Artur - 02-01-2005

Hi,

I really need some help to rip the 42S Rom to my 48GX so to my PC.
I ready the Pioneer.txt file from HP42S.COM site but is a bit advanced to me.
They say:
"You have to enter the digits in the 2nd column just behind the address."
And a long list starts:

Saturn Assembler Dump Lewis Pioneer ROM over IR Fri Feb 13 23:01:03 2004
V3.0.8 (12/06/2002) ROM42.a Page 1

SHOULD THIS PART BE TYPED IN THE CALCULATOR ??????
IF SO, WHICH COLUMN?
* Send character in A[B] over IR
*OUTBYT EQU #0133C (HP17B rev. A)
*OUTBYT EQU #01378 (HP17B rev. B)
*OUTBYT EQU #01445 (HP17BII rev. B)
*OUTBYT EQU #0136A (HP27S rev. A)
*OUTBYT EQU #0142E (HP27S rev. B)
*OUTBYT EQU #0318D (HP42S rev. A)
OUTBYT EQU #031D6 (HP42S rev. B/C)


AND THIS ??????????????
* no. of 128 byte blocks
PRGLEN EQU 512 (HP27S/42S) = 64KB / 16 min
*PRGLEN EQU 768 (HP17B/17BII) = 96KB/24 min

OR MUST I START HERE????????????

00000 D2 C=0 A
00002 135 D1=C ROM Start address
00005 D1 B=0 A init block no.
...
00062 11C C=R4
