It has two internal double-sided floppy disk drives and is the last model descended from the 1977 Model I.
It retailed for $1,199 upon its introduction in 1985.
During 1987-1988, retail stores removed the Model 4D from display, but it was available by special order until 1991.

The Macintosh Plus is the third model in the Macintosh line. It was based on the case of the 128K and 512K Macintoshes with a 9-inch display (512x342 pixels, monochrome), but with more memory (1 MB, expandable to 4 MB), a larger ROM (128 KB instead of 64 KB), and a SCSI interface, through which external hard drives and data exchange drives could be connected, as well as a SCSI Ethernet adapter. The case was initially beige in color and later became available in platinum gray.

It was the first of what would become the second generation of Macs, in which the display was an external component of the computer and no longer integrated into it.
It was the first Mac to have a color display.
It had a highly modular system, with the video card in a NuBus-type slot, allowing it to be replaced with a third-party card to achieve millions of colors on screen.
It was equipped with a Motorola 68020 microprocessor running at 16 MHz and a 32-bit bus (compared to the 8 MHz and 16-bit bus of the 68000).

Innovations: They introduced the MCA bus and the connection
for the keyboard and mouse interface, which was also called "PS/2."

The PS/2 keyboard interface is electronically identical to the widely used PC/AT interface, but instead of the 5-pin DIN connector, a 6-pin mini-DIN connector is used.
The mouse interface is physically identical, but very different from the RS-232 used until then.
Adapters existed for both connectors.
And since both connectors (keyboard and mouse) were identical, Microsoft, with the PC 97 standard, assigned them different colors.

Today, the connection of these peripherals has been almost completely replaced by USB.

They were also the introducers of the new VGA video standard.

The PC 300GL series used Celeron, Pentium I, Pentium II, and Pentium III processors throughout its lifespan. Celeron-based models had processors clocked at 333, 366, 433, 466, 500, or 533 MHz; Pentium I models had processors clocked at 133 or 166 MHz; Pentium II-based models had processors clocked at 350, 400, and 450 MHz; and Pentium III-based models had processors with clock speeds of 450, 500, 533, 550, 600, 667, 733, 800, or 866 MHz.

These systems came in two case types: desktop and microtower.

There were two variants of the desktop case, one with two expansion slots and the other with four. Both variants had four drive bays.
The microtower case had four expansion slots and four drive bays.
