This model of the PS/1 Pro had a very limited run, and contained three ISA slots instead of the usual two of other models in the series. The PS/1 Pro was, along with the junior, a more limited version of IBMs business line the PS/2.

Intended for new computer users and based on the architecture of the AT, with ISA, VGA and IDE. It was sold through stores alongside rival machines.

American machines came with a modem on board, which could access the IBM help centre. Earlier models came with a ROM installed that contained IBM DOS, but the machine was also fully compatible with other operating systems.

These were some of the first machines that had a rapid restart feature to come on after hibernation.

The machine has a 386/SX processor on board, along with a 387 maths co-processor and 2MB of RAM. It has Windows 3.1 Installed.
