This is ROMDump, a utility to dump the ROM of ANY HP48
|
|
======================================================
|
|
|
|
|
|
Usage: (2:hxs, 1:hxs --> ) pop start address from level 2,
|
|
pop end address from level 1, and dump
|
|
ROM to the serial at 9600 baud using
|
|
lines of form "aaaaa:hhhhhhhhhhhhhhhh\n\r"
|
|
with 16 nibbles ROM data hhhhhhhhhhhhhhhh
|
|
at address aaaaa.
|
|
|
|
|
|
- Download the file ROMDump to your HP.
|
|
|
|
- To capture a complete ROM, start kermit on your computer,
|
|
set the line so that it fits your HP (use speed == 9600)
|
|
and type 'log session', then 'connect'.
|
|
|
|
- On your HP48 S/SX type '#0h #7FFF0h ROMDump' or on the G/GX
|
|
'#0h #FFFF0h ROMDump'. This will give you a complete ROM dump.
|
|
This will take about 15 minutes on the S/SX, 30 minutes on the G/GX.
|
|
|
|
- When done, type the kermit-Escape (usually CTRL-\) followed
|
|
by 'C' on your Computer. Say 'quit' to the kermit.
|
|
|
|
- Your ROM should now be in the file 'session.log'.
|
|
|
|
|
|
|
|
- To dump a certain range of ROM, enter the start-address in hex
|
|
and the end address in hex, and press 'ROMDump'.
|
|
|
|
(For example: '#7FFF0h #7FFFFh' ROMDump will output
|
|
"7FFF0:84054383D21467BC\n\r" on a Version A S/SX.)
