The VAX 9000 was a high-performance ECL-based VAX.

Hardware

The CPU was built out of MCUs, or Multi-Chip Units.

Each CPU was implemented with 13 Multi-Chip Units (MCUs), with each MCU containing several emitter-coupled logic (ECL) macrocell arrays which contained the CPU logic. The gate arrays were fabricated in Motorola's "MOSAIC III" process, a bipolar process with a drawn width of 1.75 micrometres and three layers of interconnect. The MCUs were installed into a CPU planar module, which accommodated 16 MCUs and was 24 by 24 inches (610 mm) in size.
