Apple Macintosh 512K with 128K ROM upgrade, Dove MacSnap 1MB RAM and SCSI expansion, upgraded internal 800K floppy drive, external Apple M0130 400K floppy drive, keyboard, mouse and vintage carrying case.

This is an unusually well-equipped Macintosh 512K that received several desirable period upgrades while retaining its originalMacintosh 512K M0001W case and badging.

The machine has been upgraded with128K Macintosh ROMsand an800K internal floppy drive, giving it the major functionality associated with Apple’s later 512Ke configuration. It also has aDove MacSnap memory expansion providing 1MB (1024K) RAM, confirmed by the Finder as shown in the photos.

ADove MacSnap SCSI expansionis also installed, providing a DB-25 SCSI connection at the rear of the Macintosh.

  • Dove MacSnap SCSI expansion
  • Upgraded 800K internal floppy drive
  • Apple M0130 external 400K floppy drive
  • Macintosh keyboard

  • Vintage padded carrying case

    • The Macintosh boots and operates normally. It recognizes the full1024K RAM, and both the internal 800K and external 400K floppy drives have been tested and are working.

    Cosmetically, the system presents extremely well for its age, with relatively little discoloration. Please see the photographs for exact condition.

    This is a particularly interesting example of an original Macintosh 512K that was substantially upgraded during its working life rather than replaced with a later machine. The combination of128K ROMs, 800K floppy support, 1MB RAM and SCSImakes it considerably more capable than a stock 512K while preserving its original 512K identity.

    Software pictured is shown for demonstration purposes unless specifically stated as included.

    Vintage electronics are sold as-is. The system has been tested as described, but no guarantee can be made regarding the future operation of original components.
