NetBSD/sun3 runs on these **sun3** and **sun3x** architecture machines:

The **RAM** column is maximum supported RAM in megabytes.

Sun made a variety of VME bus cabinets with different numbers of bus
slots; ultimate RAM and I/O expansion is more a matter of how many bus
slots there, rather than the particular CPU you have.

The Sun3/80 RAM capacity varies with the boot ROM revision - 3.0.2
allows 40MB, 3.0.3 allows 64MB.

The Sun 3/50 has 4MB soldered on the motherboard; all RAM expansions
for that workstation were provided by third-party solutions (read
"hacks") of one kind or another.

The Sun 3/E is a 6U VME single-board computer intended as an embedded
system component.

The Sun 3/80 workstation and Sun 3/400 series servers are **sun3x**
architecture machines based on the [Motorola 68030
CPU](http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=MC68030).
They were Sun's last design using Motorola microprocessors, and were
somewhat complicated by the fact that the mc68030 has an integrated
MMU in the CPU chip.

Sun Microsystems stopped designing systems with Motorola
microprocessors when their own SPARC CPU design became a commercial
success.
