Correct behavior The Mexican way (Baedeker's Travelware, 84)

[toinet]

#984 - This is a social studies eduware. Anyone who travels to a foreign country knows how easy it is to commit social blunders, as cultures and customs are different.

Disk structure
This is a nearly standard DOS 3.3 single-sided floppy disk. There are two floppy disks.

Protection type
The disk cannot be copied. A further analysis with the bit editor of Copy II plus shows a change of the epilog markers in the address and data fields:
- address field: D5AA96 FFFF instead of D5AA96 DEAA
- data field: D5AAAD FFFF instead of D5AAAD DEAA
There is also a jump to a widely used protection check at $BB00 that counts nibbles and compare results.

How to copy
Boot my copy disk and launch Advanced demuffin
Enter the monitor
