Forth on 71B Message #1 Posted by Kim on 4 June 2001, 1:33 a.m. For some time I have been having a desire to use my 71b for something more than just Basic and was looking for the Forth ROM. In a round about way I got hold of a 41-translator ROM and to my great surprise I found that it seems to have the entire Forth/text/asembler/compiler package that was in the Forth ROM. Can anybody confirm wether that is true or there - indeed - are some differences. Greatfull for any answer Kim

Re: Forth on 71B Message #3 Posted by Reinhard Hawel on 5 June 2001, 4:19 p.m., in response to message #1 by Kim The Forth/Assembler ROM includes the Assembler part - The debugger was available seperately on thisk at a later time. The complete package was the Forth/Assembler/Debugger package. The Translator Pack includes a HP41C (CV?) emulator. I'd bet, that you could enter the assembler software via keyboard, if you have the FORTH IDS from CHHU. The Forth IDS includes a complete listing of the Forth kernel (including the assembly language part), but not the debugger. I've never tried this, because I own both ROMs, so there was no need for it.

From what I have figured out so far the Assembler is in fact missing in the Translator ROM... Cheers, Richard P.S. I am willing to pay nearly everything ;) for the Forth/Assembler ROM manuals...

Re: Forth on 71B Message #5 Posted by Richard Kurz on 14 June 2001, 7:44 p.m., in response to message #4 by Richard Kurz Stupid me... I just figured out, that the HP 71 Forth/Assembler manuals are on the Museum CDs, my version is just outdated. Time for the update ;) Cheers, Richard

Re: Forth on 71B Message #6 Posted by Reinhard Hawel on 14 June 2001, 11:11 p.m., in response to message #4 by Richard Kurz The manual is of a low value for the programmer. It's just a collection of short references. The only assembler example is a function returning a constant. This is the simplest program possible on a 71B.

Re: Forth on 71B Message #7 Posted by Raymond Hellstern on 15 June 2001, 1:46 a.m., in response to message #6 by Reinhard Hawel Yes, maybe the HP-71 IDS are on the museum CD's, too. Many years ago, I had copies of the IDS, which were a valuable source (at least for me;-) Raymond For those who don't know the IDS: The software Internal Design Specs contained listings of the source code of the HP-71 OS, and the extension modules (e.g. FORTH). There were hardware IDS, too.
