Contemporary computers of IBM PS/2 Model 25 (8525)


Manufacturer: Commodore
CPU: Motorola 68000 @ 7.14 MHz


This low-cost Commodore, aimed at the home market, was a huge success in Europe, where it dominated the computer video game market, rivaling the Sega Megadrive and Super Nintendo video game consoles.

Manufacturer: IBM
CPU: Intel 8086
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.

Manufacturer: Apple
Launched: Mar 1987
CPU: Motorola 68020 @ 16 MHz


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).
