In Figure 2, we compare the Macintosh Plus to a 21-inch LCD monitor.įigure 2: The Macintosh Plus compared to a 21-inch LCD monitorĭifferently from the Apple II and Apple III, the keyboard was not part of the body of the computer. Nowadays, the first thing you will notice looking at the Macintosh Plus is how small it was. However, in January 1987, its color was changed to the light gray color (called “platinum”) that Apple started using on its computers from then on. Originally, the Macintosh Plus was released in yellow, just like the Macintosh 128K and the Macintosh 512K. The Macintosh Plus came with an 800 kB 3.5” floppy disk drive. The first models of the Macintosh 512K (part number “M0001W”) also used a 400 kB 3.5” floppy disk drive, but later models (part numbers “M0001E” and “M0001D”) used an 800 kB 3.5” floppy disk drive. The Macintosh 128K used a 400 kB 3.5” floppy disk drive. In fact, in January 1988, Apple released models of the Macintosh Plus with 2 MB or 4 MB of RAM.Īnother difference between the three models was with the floppy disk drive. However, while the first two models didn’t allow the user to add more memory, the Macintosh Plus uses SIMM-30 memory modules, allowing users to expand the memory up to 4 MB, as we will explain. ![]() The main difference between the three models is the amount of RAM (128 KB, 512 KB or 1 MB). They were all based on the Motorola 68000 microprocessor, which was one of the most powerful CPUs available at the time, and had a 9-inch black-and-white video monitor with a resolution of 512 x 342 integrated on the computer’s body. Thus, we can consider these three models as the first generation of Macintosh computers. The original Macintosh (Macintosh 128K), the Macintosh 512K, and the Macintosh Plus had the same basic design. ![]()
