sys(2017) shows the startup screen. The checksum function is 2007.
And no, that is not the way a Checksum works. Different strings of indefinite length are all assigned a 2-byte value. Therefore, it is obvious that different strings can result in the same checksum.
The idea of a checksum is to check the validity of a password, for example. You can "encrypt" the required password with the checksum function (note: I don't think the standard checksum is particularly safe for this), and then check the checksum of the password provided by the users. If the two are the same, it is very probable that the correct password was provided.
