Tools to Convert ROM Images

ROM images?

To run an emulator like NutEm you must transfer ROM images from the calculator and plug in modules you own. The format used in NutEm differs from emu41. Here are the tools to convert the files - some even trilingual.

Trilingual?

Some of the programs are written in "trilingual" REXX, ready to run on three different platforms: CMS (IBM host), PC-DOS 7, or on any other DOS if you installed bREXX from Vassilis N. Vlachoudis. He augmented his very fast implementation of REXX to make this possible. Look for his bREXX newer than 2.0b.

The formats of ROM images

I know four different formats:

ZEN (or HPM) - this is the print out of the ZENROM's disassembler and looks like this (only the 2nd word is used):

D5EF 2A0 SETDEC
D5F0 130 LDI
D5F1 003 CON    03
D5F2 0BE A<>C   S
D5F3 21E C=A+C  S
D5F4 01B JNC    +03 D5F7
D5F5 046 C=0    X
D5F6 23E C=C+1  S
D5F7 03C RCR    3
D5F8 3EE ASL    ALL
D5F9 3D4 -PT
D5FA 194 ?PT=   11
D5FB 037 JC     +06 D601
D5FC 394 ?PT=   0
D5FD 39B JNC    -0D D5F0
D5FE 33C RCR    1
D5FF 1A8 REG=C  6/N
D600 383 JNC    -10 D5F0

JFG - the format J. F. Garniers uses in his BIN files. No example given as it is binary.
LIF - originally this stands for Logical Interchange Format and is the way HP formatted disks in some elder devices. On such disks you may store with the RAMBOX-command WRTPG a ROM image. This may be transferred to DOS with appropriate programs from HP (I`ll insert a link to LIFUTIL when I find it again).
DMP - short for dump. I do not count it as a format of its own as it is too close to LIF, it's just a disk-dump from a ROM image written to an LIF-disk with WRTPG. As disk-dump program I use VLIF of JF Garnier.
EPR - short for EEPROM (or U2/L8), a format used in MLDLs.

The names of the translation programs are build with the above mnemonics and the "2" (pronounce: to) to show the direction of translation. Therefore, the program LIF2ZEN will convert an appropriate LIF file to its ZENROM disassembler-listing equivalent (w/o disassembling).

This ZIP contains the QPL Public License and following programs:

Trilingual Routines (CMS, PC-DOS 7, bREXX)

JFG2LIF EXEC LIF2ZEN EXEC Note: There is no need for a trilingual ZEN2JFG, on DOS use CLBIN41.EXE from JF Garnier.

Tools for CMS only

with Pipeing

LIF2HPM EXEC DMP2HPM EXEC WPG2HPM REXX JFG2HPM EXEC JFG2HPM REXX EPR2HPM EXEC HPM2JFG EXEC HPM2LIF EXEC

without Pipeing

JFG2LIF EXEC LIF2ZEN EXEC ZEN2JFG EXEC

What to do with this Package?

Transfer the download from above binary to your VM on a disk of your choice, run following commands:

pipe(sep |)< conrom vmarc | fblock 80 | > conrom vmarc A F 80 vmarc unpack conrom vmarc A = = A

In both commands replace A with the letter of the MDisk where you like to store the files.

Note: the a. m. ZIP contains a VMarc file. Without access to VM/CMS you may use VMAwin by Leland Lucius.
