This smaller and more robust floppy disk than the 5¼" one would end up becoming more portable from 1982 onwards, when it was incorporated into the Sony SMC 70 computer, and a year later, the HP-150 and Sony's MSX computers.

It was the first update to the original Macintosh 128K.
It was identical to the previous Macintosh, differing only in the amount of RAM (random access memory) it included.
This allowed it to run more complex software, giving it greater business capabilities.

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.

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.

For the creation of its first laptop, Apple based its design on the Macintosh SE of the time.

Next to the keyboard, it included a novel trackball.
