120 Words Block Format for Mailbox In Message (Input Image)
When the Block Transfer Size = 120, it takes two Output blocks to form one
complete mailbox message request. Each Output block will be responded to with
a corresponding Input block with the same ID number.
Note: Since the same two Output Block IDs are always used for 120-word block format requests,
the Input Block IDs will always be the same two numbers, as well, 100 and 101.
