The RAM column is maximum supported RAM.

The Arch is the system architecture which includes things like the MMU design, various system busses, etc. Not listed here are the sun4d (Sun Enterprise servers), and sun4u (UltraSPARC) system architectures. I'll get to them one day.

Some of the systems are in a series; in particular the Sun 3/100, 4/100 and so on. There are a number of models in each category that indicate a specific system configuration; not all of them are listed here in both the interest of brevity, and because for the columns in this table, they are undistinguished.

All Sun RAM requires parity bits. Attempts to use typical non-parity PC SIMMs will fail.

Older Suns were based on the Motorola MC68000 family of 32-bit microprocessors. The SPARC is Sun's own 32-bit RISC design, with fabrication provided by various vendors. The UltraSPARC is a 64-bit processor.
