Note that disks are mislabeled in EaaSI: 'disk 1' in EaaSI refers to '1531-3 (Program Disk 2)' from NSRL photos; 'disc 2' refers to '1531-2 (Installation/Program Disk 1)'; 'install disc' refers to '1531-1 (Help and Examples)'.
This is a DOS software, but it's not clear what version of DOS is the minimum version.
The 'about' menu says that the program requires 710 kb (0.71mb) of hard disk space and 1008 kb (1.008 mb) of XMS memory. Since XMS memory seems to refer to memory used above 1 MB, I assume this means the program in total will take 1 MB + 1.008 MB = 2.008 MB. This is what I noted.
I'm guessing that *.sks is a proprietary Sidekick file format. Again, I'd advise taking the information about saving files with a grain of salt. I went through a bunch of menu options, but I don't feel confident in saying there's not some hidden functionality I couldn't find.
The 'help' notes also indicate that this program comes with a program called SKCONVER, which converts Phonebook and Time Planner files from Sidekick 1.0, Sidekick Plus, and Sidekick for PM. I didn't have any of these old file types to test out the program, but it's worth noting that this functionality exists.
