The Macintosh Classic was released in 1990 and ran until 1992, though runs the same 8MHz Motorola 68000 found in the earlier Macintosh Plus and Macintosh SE models. Similar to the SE model, the Classic has room for an internal hard disk. The Classic wasn't an overly remarkable computer, but we believe it was designed to be a low cost solution ideally for the education market. As a result, the Macintosh Classic was commonly found in schools during the early to mid 1990s.

Secret ROM Disk

There is an embedded copy of Apple System 6 stored in the ROM. Hold down Command + Option + X + O during power-on to boot off the ROM disk.


  • Due to the age of this computer, modern usage requires the logic board have the capacitors replaced and the PRAM battery removed or replaced. Capacitors on the analog board may also need to be replaced if you experience issues with the display.
  • Another potential Classic issue is the failure to complete the "POST" sequence and the system will stop loading just before the point where the "happy Mac" or blinking disk icon would show up. We suspect this is the result of a defective SCSI bus.
