smaller HP 82166A with 32-pin connector

Thanks J-F,

I actually use the address as you suggest.

I admit, that I am struggling with the logic of R0 to R3. I get most of it, but not all.

As G. Friedman suggest, the documentation and examples from HP were not exactly the best he had seen.

I saw a reference to Christoph's book HP41 - Input-Output Board and the TOC - looked like what I needed. Can't find it anywhere to buy. Maybe someone here would know how to get the book or how to get in touch with Mr. Klug (means clever in German )

Here are the 2 pieces I use for my experiment - retyped.

The listener stops at line 20 and move no further

Code:


1 !LISTENER
2 RESTOREIO
5 A=DEVADDR(“%64“)
6 ! FROM CONTROL THE WORLD P178 – LOOKS CORRECT 
7 SEND UNT UNL MTA LISTEN A DDL 0 DATA 226,16,24 UNT UNL
10 FOR I=1 TO 10
20 ENTER :A ;B$
25 DISP B$
30 NEXT I 

1 !TALKER (sends CHARS - seemingly)
2 RESTOREIO
3 ENDLINE””
5 A=DEVADDR(“%64“)
9 ! FROM CONTROL THE WORLD p33 – LOOKS CORRECT
10 SEND UNT UNL MTA LISTEN A DDL 0 DATA 74,16,208 UNT UNL
20 FOR I=1 TO 63
25 X$=CHR$(I+64)
30 OUTPUT :A ;X$
31 DISP I; X$
40 NEXT I

First of all, you must use addresses in OUTPUT and ENTER statements, not just :LOOP.

Please post you complete test sequence, so we can evaluate it.
