Question of the Day

Yesterday we asked: Many computer Easter Eggs are fun little surprises, but others are a bit more practical. Apple came up with this one—revealed by typing a secret six-digit hex address into the debugger—in the early 1980s to protect against potential Mac clones. What is it?

Answer: That was the “stolen from Apple” icon (or text in some systems), which Steve Jobs thought would be an effective form of proof at trial if another company copied the Mac ROM to their computer.

Congrats to Dan Rosenbaum, who even mentioned the hex address, 4188a4. Go ahead and try it out on your old Mac IIcx!

Your question of the day for today is…This year marks the 50th anniversary of the Monterrey Pop Festival. Several performers famously missed the 1967 festival because they were unable to get visas due to drug arrests. What band was refused a work visa due to their dispute with the American Federation of Musicians?
