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.

The Emu71Win installation does not include the system ROM image, nor any of the optional images. You'll need to download any ROM images of interest from Sylvain's HP-71B Compendium.

Extract HP-71B_OS2CDCC_ROM.BIN from HP-71B_SYSTEM.ZIP, copy the file to the installation directory for Emu71, usually C:\Program Files (x86)\HP-Emulators\Emu71, and rename the image to match the one specified in the KML file, HP71B.ROM.

See sections 4 and 5 of the Emu71/Win manual.

"Dump the EPROM using the procedure in the Emu71/Win manual"
are you referring to "3.ROM Images" in the manual?

Precisely. ROM's and EPROM's are treated the same.

"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?

The file at the address you're PEEK$ing is protected. The solution is to install a LEX file that provides an unrestricted PEEK$/POKE instructions. JPCF05 and DESAL are two examples. JPCF05 needs to be installed, either as a ROM or LEX file.

HTH, Dave
