Re: Transferring files between HP 41 and PC using serial interface Message #11 Posted by Christoph Klug on 15 Nov 2004, 4:13 a.m., in response to message #10 by Garth Wilson
Dear HP41-PC interfacing enthusiasts :-)
A small companie called Handheld Portable Products = HPP produced a special version of the HP82164 RS232-IL interface which is battery powered for mobile applications.
Also CMT produced a very nice device, called IL-RAM-Disk unit, which includes a RS232 interface option. Also this device is battery powered for mobile applications.
Actual the standard Windows solution for interfacing HP41 to PC by using RS232 is the software form Hans Brueggemann. As I know Tony Duell created a software solution for Linux operating system.
Alternatively you can use the HP-IL/PC interface card for interfacing your handheld to PC world. For this some different software solutions exist : HP41.com LINK PLUS, TRANS41 EMU41 and EMU71. By taking this solutions you are able to interface HP41, HP71 and HP75 handheld computer to PC world.
For parctical work with HP41 I prefer using EMU41, because this powerfully software is an advanced emulator , includes some virtuaL IL-Devices and also acts as HP-IL controller for controlling real IL-Devices.
For EMU41 exist user code software solutions for transfering any tpye of HP41 files (data, programm, ASCII, CCD-Module matrix files and NNNīs = non normalised numbers). Also EMU41 includes up and download of complete HP41 rom images (plug in modules). This is helpfull for creating own rom solutions and for programming new hardware devices like CLONIX or NoVRAM...
