This is ROMDump, a utility to dump the ROM of ANY HP48
======================================================

[Note: This dumps ROM in hex "memory scanner" format with an address
at the beginning of every 16 nibs.  This is the format Voyager's
DMPTOMEM program requires (see DMPTOMEM.DOC on GD2).  -jkh-]

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.)
