HP-71 Compu-LS module

[twa14]

Hi Dave/Christopf/JF

The PIL-BOX is up and running but I still have lots of questions. I am using win7 32 bit in a VMware virtual machine for Ilper\Emu71/Win. I understand that 64 bit OS is not possible?.

When I try to run EMU_71 (windows version) I get the error message shown in the attachment.

Dave, you say in your instructions:
"Dump the EPROM using the procedure in the Emu71/Win manual"
are you referring to "3.ROM Images" in the manual?

Christopf says:
"Insert this information into the ROMDMP BASIC program"
I have used the following code with"COMPU" in the place of "JPCF05":

10 DIM A$[64]
20 A=IP(HTD(ADDR$("JPCF05"))/256)*256 ! start address of JPC ROM to transfer
30 FOR I=0 TO 32*32-1 ! length of ROM (here for 32Kb)
40 A$=PEEK$(DTH$(A+I*64),64)
50 OUTPUT :1 ;A$
60 NEXT I

I get an error line 40: file protect?

At first I used the code out of the manual under "3 Rom Images" and that worked in Ilper!
A stream of hex codes was being produced in the Ilper screen until I cancelled the program

What must I do to get past the file protection?
