Can anyone assist me with the best process to take HP-41 programs and convert them to text format so the HP-71B can read them?
Please let me know.

Connect both the HP-41 and the HP-71B via HP-IL,
Maybe setting the HP-71B to act like a printer could also help (PRINTER IS: HP71) . HTH Raymond

Are you trying to run the 41 programs on the 71 using the HP-41 Translator Pac? If so, use the READ41 program in the Translator Pac. Other than that, if you have an 82164A HP-IL to serial converter, you can use the PRP ("PRint Program") function to send the program as text to the serial converter, to be captured on any kind of computer with a serial port. If you have either the 82164A or a 9114 disk, you use Tony Duell's life_utils on a PC running Linux to capture and decode it (lifget and prog41). Perhaps someone has ported lif_utils to Windows or DOS, or perhaps equivalents exist.

That general approach works fine, and is in fact what the READ41 program in the Translator Pac does, but I don't think the "PRINTER IS" statement is necessary or helpful.

The 'PRINTER IS..' was a guess, but as I think about it,

Also EMU41 (in combination with the HP-IL/PC Interface Card) includes the possibility to print HP41 programs inside an ASCII text file.... Best regards - Christoph KLug

It has been a long time since I've done this, so I might be forgetting some details. I think your error message comes from the 41's going out on the loop and looking for something that looks like a printer, and not finding it. If you do
1 before "printing", you will be telling it exactly which device to use. That assumes that the 71 is the first device on the loop. If it's not, change the number accordingly.

The trick here is to do MANIO on the HP-41C, otherwise the HP-41C searches for a printer, and there is none.
And of course, the HP-71B has to do a lot of ENTER statements to read all the program lines. You could do something like: 10 ENTER :LOOP;A$ J-F

That MANIO did the trick. The key is to get the data to save to a text file on the HP-71B. Will work on that tonight. All I need to do is convert the programs for a friend to load from the 9114 drive to the HP-71B. Any help on the program would be appreciated. |
