HP-41CL Remote Keyboard / Scripting

[Sylvain Cote]

With the following configuration you could have a starting point using FOCAL

Hardware & software:

Code:

HP-41   → calculator
82160A  → HP-IL module
82183A  → Extended I/O module
PIL-Box → HP-IL-to-USB interface
        → Any HP-IL peripherals emulator that has a console/keyboard emulator (I will use pyILPER for my example)

My HP-IL loop config:

Code:

loop address 0 : HP-41 controller
loop address 1 : pyILPER terminal emulator
loop address 2 : pyILPER printer emulator
               : pyILPER scope configured to see incoming and outgoing HP-IL frames to see the polling and the responses

HP-41 Input from remote keyboard example:

Code:

AUTOIO    // reconfigure the loop
1         // keyboard address
SELECT    // select device
65        // stop character, here ASCII 65 or 'A'
INAC      // Ext-I/O function, activate loop polling and ALPHA filling until full or until stop character received
AVIEW     // show received data

In pyILPER terminal windows type:

Code:

QWERTYA

On the HP-41, ALPHA should contains:

Code:

DQWERTY

There are several HP-IL input functions in Extended-I/O ROM, read the manual and use your imagination to surprise us !
