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.)
