Hello:
Now that I've gotten EMU41 to run properly under XP on my P4 machine, I've begun moving my programs from magnetic cards to both floppy and PC storage. Moving files to and from the 9114B using EMU41 works great. I've left the hdrive1 declaration in the EMU41.INI file to try to save files to virtual mass storage file but that hasn't worked for me.
I tried renaming the hdrive1 file but that made no difference as well as deleting and generating a new hdrive1 file via NEWM 100. Finally, I commented out the XIL 300 in the INI file and then EMU41 would properly save files the virtual mass storage device in the hdrive1 file.
It appears to be some kind of conflict between virtual mass stroage and the 9114B though that doesn't make sense as J-F planned for both internal and external HP-IL devices and they both have separate address IDs and you can have multiple mass storage devices on same HP-IL loop. Has anyone seen this behavior before? I've sent an email to J-F yesterday but I haven't heard back from him yet. I also searched the HP Museum website but found no specific mention of storage issues between virtual and real mass storage devices in EMU41.
It's very possible that J-F never saw any reason to have both virtual and real mass storage devices in use at the same time when he wrote EMU41. If you have a real disk drive connected to the PC, why would you ever need virtual storage? This is a pure guess on my part though. My reasoning for wanting to save files to both devices is that as useful the floppy storage is, I believe strongly in backing up files. I'm thinking of having multiple hdrive1 files with all my programs on them so that in addition to my floppies, I can back up the hrive1 files when I do a PC backup. Also, the 9114B floppy file format is non-standard with Window or Mac PCs so I can't use a regular floppy drive to copy the files to a PC.
Finally, I could just be doing something wrong. I don't have a copy of my EMU41.INI file with me but it's a standard HP-41CX setup with Extended Functions, Time, Printer and HPIL controller along with the Advantage ROM. My declared HP-IL devices are Display, HDRIVE1, FDRIVE1, LPRTER1, DOSLINK and XIL 300.
Any insights are appreciated.
Thanks everyone,
Gerry
