Age 15. Apple II+ The discussion here brings back a lot of fond memories. The Apple II was a great computer and easy for a teenager to understand. Source was available for almost everything (and what wasn't officially available had been disassembled and documented with high quality.) Here's something other HN members might enjoy: Got access to an old Apple with Applesoft BASIC? Try this: CALL -151 300: AD 30 C0 E6 B8 D0 02 E6 B9 4C B7 00 B1: 4C 00 03 3D0G Now, run any BASIC program and listen. You'll quickly discover you can tell what the machine is doing. Floating point? Rapid ticks. Tight loop near the beginning of the program? High-pitched whine. Great for debugging or simulating a background thread.
