first Macintosh computer by Apple

Introduced in January 1984 (along with a revised Lisa ), this Macintosh didn’t have a model number – it was simply the Macintosh . There was no name on the front. Early 128Ks simply said Macintosh on the back, while later ones were marked Macintosh 128K to distinguish them from the later Macintosh 512K .

Equipped with 128 KB RAM, 64 KB ROM, a 3.5″ 400 KB floppy drive, a 1-bit 512 x 342 pixel b&w monitor, a mouse, and a couple applications (MacWrite and MacPaint), the Macintosh was destined to change the face of computing forever – it not only created the Mac look and feel, it also inspired forthcoming versions of Microsoft Windows and several other windowing interfaces.

What didn’t it have? A SCSI port, 5.25″ floppies, backward compatibility with the Apple II, III, or Lisa.

Insert the disk you are copying to. If necessary, DiskDup+ will format the disk. If the newly created disk is unreadable on the old Mac, try making a copy on another machine (this can be cause by a misaligned hard drive). DiskDup+ will work on old machines with 1 megabyte of RAM; it will require two passes to duplicate the disk, however.
