Need help with HP82164A HP-IL/RS232 Interface



#13

Hello! I'm new user of HP-71B. I'm student and I use it heavy for my studies.I've computer with RS232 interface. I lost many useful programs and need type it again. Somebody can help me found easy way how to save/load my programs to/from PC. I don't know with software and what a commands I've to use.
With respect,

Wow! Why? Of all the modern options why the 71B?

IIRC, here is the general idea:
  1. Install EMU71 (free version, http://www.jeffcalc.hp41.eu/emu71/index.html). Get all your programs running in there (you can cut/paste them in or use DOSLINK, read the EMU71 docs).
  2. Make this cable: http://www.jeffcalc.hp41.eu/emu71/files/serialcable.pdf. Run the little 71B program at the end of the doc on your 71B. Then connect the IL-RS232 device to your PC.
  3. Configure EMU71 to use the serial port the IL-RS232 is connected to.
  4. From EMU71 type COPY PROGRAM TO SERIAL1:
  5. From 71B type COPY :HP82164A TO PROGRAM
The above may or may not work, I think I have done it once. I have not had to rely on this method because I have an ISA HP-IL adapter in an old PC for this type of work. However, that recently changed with the introduction of the PIL-Box (USB to HP-IL, http://www.jeffcalc.hp41.eu/hpil/index.html).

There's a reason some of us keep asking that HP go back to what they used to have. Their newer offerings are not better than the old. My 71 with its modules, extra 160KB of RAM, many LEX files from the user groups, and better manuals is worth far more to me than my 50g. AFAIK, there are precisely zero modern handheld options that can act as a lab instumentation controller.

Well said, I'm on the same track here.

Nevertheless it's quite interesting finding this to be the choice for today's students - if not for anything, consider how unknown the old systems are - or at least I thought so.

Hola, Ángel; ¿que tal?

If the old systems are actually unknown at a certain extent (and I agree with that), what can we say about the new ones, with billion times more system and virtual memory than the old ones? Who'd dare explaining, or even understanding, a source code generated by a sub-code from a builder after some newbie (wannabe?) 'explains' the system what he believes he wants the system to do in a dozen lines? The idea scares me!

Cheers.

You and I are biased having been there, done that. I'd like to know why a 20-something (assumed) student independently determined that the 71B in 2009 best fit his needs.

The 50g AUR is actually quiet good and searchable. The size of the user contributed code for the 50g from hpcalc.org and other sources easily eclipses the 71B. The 50g has modern I/O options. And there is a very good 71B emulator for the 50g.

I am not trying to say the 50g is better or to argue that the 71B is not best for you, but someone making a comparison in 2009 would most likely select the 50g.

I know nothing of this space, but I'd wager that the percentage of people that care about such things rounds to zero. Simply because if a larger percentage cared then the market would (should) meet demand.

So I've sensed, at least from this forum; but it makes me wonder why anyone would want a ton of speed and memory if they can't get a ton of data into it quickly to operate on, by reading it over an interface from instrumentation, and can't do anything useful with the voluminous results except maybe view a little of it in a small built-in screen. So what gives?

Hi Egan!
Thank you for your answer. In our university forbidden use of modern graphical calculators on exams. Only non-graphical. We've a lot of matrix and others calculations. I wrote many programs in basic what help me very much. Usually I use Sharp PC-E500, but it has a graphical display and can't be used in exam. The HP-71B looks a great machine but save/load is much complicated. Regarding to EMU71, I tried it and it not working. Don't know why. Could you advice another terminal program?

With respect,

ILYAS

Too bad the 42S was not still around. It'd be perfect.

Wow! Another oldie.

What OS are you running? What problem did you have with EMU71? Were you able to use EMU71 and run your programs? Was file xfer the only problem?

I have used Hyperterminal. But I had to write a small program to capture the text.

If I have time this evening I'll build a custom cable and give it a go.

Do you have the math ROM for the 71? It has all the matrix operations in assembly language so it's much, much faster than anything you'll write in BASIC.

The 71's display can do graphics but only 8 dots tall. I wrote Forth utilities for it to display two lines of 33 or 44 tiny characters per line. The graphics capabilities of modern calculators are of almost no value to me though.

I did not have a lot of time, but this worked for me.

Create the following programs:

T2S:

10 REMOTE @ OUTPUT :HP82164A ;"LI5;C0" @ LOCAL
20 ON ERROR GOTO 120
30 DESTROY ALL
40 DIM A$[100]
50 INPUT "FILENAME:";F$
60 TRANSFORM F$ INTO TEXT TMPFILE
70 ASSIGN #1 TO TMPFILE
80 READ #1;A$
90 DISP A$
100 OUTPUT :HP82164A ;A$
110 GOTO 80
120 OUTPUT :HP82164A ;"EOF"
130 PURGE TMPFILE
140 END

S2T:

10 REMOTE @ OUTPUT :HP82164A ;"LI5;C0;SL2" @ LOCAL
20 DESTROY ALL
30 DIM A$[100]
40 INPUT "FILENAME:";F$
50 PURGE F$
60 CREATE TEXT F$
70 ASSIGN #1 TO F$
80 ENTER :HP82164A ;A$
90 IF A$="EOF" THEN CLEAR :HP82164A @ GOTO 130
100 DISP A$
110 PRINT #1;A$
120 GOTO 80
130 ASSIGN #1 TO * @ TRANSFORM F$ INTO BASIC
140 END

Connect the 82164 to your PC with a standard null modem cable, do not use the custom cable (did not work for me).

Launch Hyperterminal, setup with 9600 BPS, 8N1, Hardware Flow, and terminate lines with LF (Hint: Properties/Settings/ASCII Setup/Send line ends with line feeds).

To backup a BASIC program run T2S, from HT just cut and paste the output into notepad.

To restore a BASIC program run S2T, from notepad cut and pasted into HT. NOTE: Your input must end with the line EOF<cr>. If not, just type EOF<cr> in HT.

There is a minor issue I did not have time to resolve, so after each transfer power off your 71B, press reset on the 82164, power 71B back on.

Good luck.

P.S. Sell your 82164 and get a PIL-Box (USB to HP-IL). It will be easier.
