- Well, the Lisa had a unique serial number in each machine; as I
- understand, it was burned into a special PROM on the motherboard.
- This was a major headache at the time, which is why it wasn't
- continued in the Mac. The biggest single problem was serviceing
- these machines; if the PROM blew, you had to special-order a
- PROM that matched the one that had been destroyed (or all your
- copy-protected software wouldn't work anymore) or have to go and
- tell a number of software companies that your PROM blew so you need
- a new unlocked copy of their program. If something else on the
- machine broke, or you wanted to upgrade, and you wanted to swap
- motherboards, you had to deal with swapping the serial PROMs too.
-
- In the end it was much more trouble than it was worth, and its
- only real purpose was copy-protection, and copy-protection is
- generally easily worked around, so it was taken out of the Mac.
