Hello Bob,

both of them, some limitation of this system and practical use.

In the source-file ildrive.h there is this row:
Code:
#define sd_maxlif 17       // max number of lif files
Maybe sd_maxlif can be set higher. The Arduino IL Drive simulator load the name of all LIF-files at startup, so there will be a point when the SRAM is full.

But more important is the practical use. At startup only the both LIF-Files first copy on the SD-card are accessible under the Name HDRIVE1 and HDRIVE2. In short as ":1" and ":2" on the HP-71B. You can switch to another LIF-File, but: At startup only the both LIF-Files first copy...

Tobie writes about this in his manual: "It’s a good idea that you will have more then one sd card. For example one for the HP41 and one for the HP71, so you don’t have to change the current LIF file for each controler."

Best Regards
Klaus
