Motorola PowerStack - was an early PowerPC workstation, produces since 1994 and was discontinued circa 1999.

Overview
This line has a internal PReP subarchitecture ; this archicecturre commonly was be used in a IBM RS/6000 workstations.

The PowerStack was one of the Motorola Computer Group's entries into the personal computer (PC) market around the time the Microsoft Windows/Intel x86 juggernaut was stumbling with their mass market Windows 3.11 replacement.

PowerStack
Also known as PowerStack Series E; This is a PowerPC-based development system, runs a 66Mhz PPC chip. For the OS it runs AIX, same os that developed for IBM RS/6000. This system also can run the PPC version of Windows NT, remarkably enough. It's a compact, modular, efficient platform featuring IBM/Motorola's PowerPC CPUs as well as best-in-class contemporary interfaces like PCI and SCSI. A compute element could be stacked with other modular I/O and storage cases to expand its capabilities without having to rehome the computer in a larger chassis.
