HP-IL and EMU71

[hesc]

Dear all,

I was using my HP71B to communicate with the 3468A multimeter. That works.

The program:
10 ! DCV HP 71/3468A
20 REAL V
30 CLEAR
40 D=DEVADDR("HP3468A")
60 ENTER ; V
70 DISP V
80 END

I was wondering if I was also able to use the EMU71 with the PIL-Box for this purpose. I installed the virtual HP-IL ROM and executed VER$. The result was OK: HPIL:1B.
I programmed the exact program in EMU71 as it worked in the real HP71 and made the connections with the PIL-box. Running the program hangs.
The EMUL71 cannot be put on again and the only way to get it working was to reset it with loss of my program.
1. How can I save the program? I tried to initialise a tape, but that did not work. I tried to back it up, but that did not work either.
2. What went wrong: why isn't it possible to turn on the EMU71 without a reset?
3. Why does the program hang?

Thank you for your reply.

Kind regards,
Henk Schellen
