ROMCOPY

[KimH]

Forgive me if this is all known, but I know this has helped others

71B connected via IL to the PILBOX

Launch ILPer - I choose COM3 and nothing more needed

Make sure the HP9114B and the HDRIVE1 has a file linked to LIF or DAT format (could be the ROM you want to copy - normally a LIF)

Start ILPer

Use the icon in the upper left hand corner of your dialogue box - Right click and you should see HP-IL Device info which shows address of the devices have available in your IL-Link "chain".

Mine is Printer on :1, HP9114 on :2 and HDRIVE1 on :3 - default

RESTOREIO on the 71B

and do a CAT :X on your 71B with X being the number of the one you have your ROM-Image in - it normally should show the ROM as a CURVEFIT ROM and the ROMCOPY as LEX - the one you know about. It also shows the size of the ROM image - in this case 32K - no way around the 32K in this approach! You must have a FREE'd 32k IRAM available to move it to the 71B or it wont work.

Getting 32K is obviously easier on a virtual 71B "EMU71" (and a lot cheaper)

Hope this helps

Jumper P2 is set
After setting baudrate to 230400 (exact value in pyILPER baud rate menu) I get an error from ILPER: illegal retval???
Can you give me the syntax for the assign io and list io statements? I am quite new to the HP71. I looked in the reference manual but could not find it.
Is it the best way to get a rom image?
