Dear John, dear HP41 enthusiasts :
nice discussion about HP41-PC Interfacing. Some different solutions exist, and may be we get some more in future ? Now I want to give you more details about the "HP41-PC gateway & emulator" which is based on EMU41 from Jean-Francois Garnier :
Unfortunately the former software solution Link Plus is limited to slow PCs like 286/16MHz machines. Software Trans41 is compatible to modern machines, also EMU41. I tested both software solutions with some different PC hardware from 286/16MHz up to fast 1GHZ Athlon machines. You need a motherboard with ISA slot, actual no solution for PCI or USB bus exist. Also today ISA is an industry standard for PC applications and some special and exotic ISA cards exist beside modern PCI systems. If you need an old ISA slot PC, may be you find one in the garage of your neighbour ?
PC-operating system :
EMU41 (and Trans41) run with DOS, WIN95 and WIN98SE. For this installation is absolutely easy. For modern operating systems like WIN2000/XP/NT you need an additional address routing software tool (tested from Leo Duran). A text help file which describes installation procedure and first steps is available from me.
Needed equipment :
You need your HP41 with HP82160 IL-Module. The non exotic IL module you get from ebay. Price is placed in the range from 20$ up to 60$. Furthermore you need the HP82973 HP-IL/PC Interface Card – or the replacement unit from me. Price for the last is 150$ plus transfer costs. You also get some documentation and nice software tools. From Jean-France Garnier you get the personally signed full version of EMU41 for a fee of 20$. This includes HP-IL features. The basic EMU41 you download free from Jean-Francois Garnier´s webpage...
Human Machine Interface of EMU41 :
Like the real HP41 also EMU41 includes a basic HMI : You get a DOS like screen display and use the PC keyboard. No mouse assistance. No photo realistic graphic design. But compatible to the great range of PCs.
HP41 – PC :
EMU41 offers you some different solutions for transfer of data, programms and files between HP-41 handheld and PC :
1. HP-IL (bi-directional) working with virtual mass storage unit
2. HP9114 IL-Disk Drive (bi-directional) Only possible for old floppy drives/PCs like 286
3. HP82161 IL-Cass Drive (bi-directional)
4. Barcode plot with EMU41 and virtual SkwidInk module (only download to HP41)
5. Under development. Actual Jean-Francois Garnier works on it...
