The information from the HP chart is presented in backwards
binary.
No. That documentation uses ordinary binary, not backwards. "Backwards" would mean the high order bits are shown on the right. But the high order bits are on the left in that doc.
From where is the x.17 for the device number derived?
The 'x' (2 or 18) in x.17 is the same bits as the system code.
The 17 in x.17 is the bottom byte of the customer code. The top byte of that is always 128 in MCE. 128*256 = 32768, so that top byte contributes 32768 of the customer code. 32768+17 = 32785 because the bottom byte is 17.
