Hi all,

exchanging files with my HP71 to/from PC incl. EMU71 and HDRIVE1 works absolutely great with u.m. specs.

However, since I'm new to the HP41 I simply did not get how to "fill" my HDRIVE1.dat with programs and data (from the software library or even from a DOS file) to transfer them to my physical HP41?

Sorry for asking such a basic question. Can anyone explain the steps required.

Many thanks in advance, Roland

my specs:
HP41CV
EMU41
HPIL Interface HP 82160A
HP-IL/PC Interface ISA Card

Why not use EMU71 and its COPY command to transfer files from :DOSLINK to :HDRIVE1 ? The 71B should understand HP-41 files.

Here is one way:

1. Setup EMU41.INI with HDRIVE1.DAT and HDRIVE2.DAT (you can use any name you like, but internally to the 41 they will be HDRIVE1 and HDRIVE2).

2. From EMU41 use NEWM to format HDRIVE1:
   

   [ALPHA]HDRIVE1[ALPHA]
   
   FINDID
   
   SELECT
   
   NEWM
   
   

3. Then use HP41UC (http://www.hpmuseum.org/software/41uc.htm) to convert your code to LIF format, then copy that LIF to HDRIVE2.DAT, e.g.:

   Say you have the following program:
   

   LBL "HELLO"
   
   "HELLO"
   
   AVIEW
   
   END
   
   

   To convert to LIF type:
   

   HP41UC.EXE /t=HELLO.TXT /l=HELLO.LIF
   
   

   Then to use with EMU41:
   

   copy HELLO.LIF HDRIVE2.DAT
   
   

4. Then from EMU41 type:
   

   [ALPHA]HDRIVE2[ALPHA]
   
   FINDID
   
   SELECT
   
   [ALPHA]program name[ALPHA]
   
   READP 
   
   [ALPHA]HDRIVE1[ALPHA]
   
   FINDID
   
   SELECT
   
   WRTP
   
   

   Once you know the IDs you can just type (assuming IDs of 3 and 4):
   

   [ALPHA]prog name[ALPHA]
   
   4
   
   SELECT
   
   READP
   
   3
   
   SELECT
   
   WRTP
   
   

You could also use DOSLINK with .DAT files with INP/OUTP, IIRC.

Dear Egan,

Please describe step 3 of your explanation more in detail. Up to now I never worked with HP41UC....

Thanks a lot for your support :-)
