[comp.arch] Sun/3 and Sun/4

john@geac.UUCP (John Henshaw) (01/17/88)

I have a simple (naive) question for my net.friends. My apologies if
this question has been answered recently.

What are the differences between a Sun/3 and a Sun/4 system?

Which is better? My criteria for an answer to this question would
revolve around architectural issues, available software, and general
compatibility. My understanding to date is that the Sun/3 uses one
of the Motorola 680x0 microprocessors while the Sun/4 is implemented
using a specialized hardware.

When Motorola arrives with their promised 68040 microprocessor, can we
expect there to be the creation of of Sun/x system using that
technology? (It seems to me that the creation and sale of non-680x0
based hardware represents an important step elsewhere.)

Please Email or post; if I get enough responses via Email, I will post a
summary.
