La matemacia con il computer
Volume 1 - Le basi
(c) 1983, VIFI Mondadori

This is an Italian educational software. It has been tested on an Apple IIgs and seems to run fine.

The program comes with one single-sided protected 5.25" floppies:

The on-disk protection relies on a change of the header markers of the data fields: D5AAxx instead of D5AAAD. xx is determined by an index value in the authorized nibble values that is calculated based on the last character of a filename. For instance, if the last character is E then the third marker is BB. That protection comes from the DOS PROTECTION TOOLKIT published by Apple. The easiest way is to format a new DOS 3.3 slave disk and copy all tracks from 3 to 34 bypassing the read of the third marker (but that is not that easy as the protection sets a specific value in the accumulator before reading the nibbles from a protected sector)
