My coworkers made me use Mac OS 9 for their (and your) amusement | Ars Technica For about $75, I was able to pick up an 800MHz model with 512MB of RAM and a 40GB hard drive. It worked but included a non-working battery, no power adapter, and a wonky power jack. For $8.86, I picked up a new power jack (happily, it was separate from the main logic board in those days), and another $15 got me a used genuine Apple adapter (third-party substitutes are widely available for a few dollars less, but I am terrified of cheap off-brand chargers). That brought my total to a little under $100.

Adventures in old-timey usage of one of the very best laptops ever made. Mine still works perfectly, although it boots in to Jaguar, not OS9.
