Sun-4 is a series of Unix workstations and servers produced by Sun Microsystems, launched in 1987. The original Sun-4 series were VMEbus-based systems similar to the earlier Sun-3 series, but employing microprocessors based on Sun's own SPARC V7 RISC architecture in place of the 68k family processors of previous Sun models.
Models are listed in approximately chronological order.
In 1989, Sun dropped the "Sun-4" name for marketing purposes in favor of the SPARCstation and SPARCserver brands for new models, although early SPARCstation/server models were also assigned Sun-4-series model numbers. For example, the SPARCstation 1 was also known as the Sun 4/60. This practice was phased out with the introduction of the SPARCserver 600MP series in 1991. The term Sun-4 continued to be used in an engineering context to identify the basic hardware architecture of all SPARC-based Sun systems.
Sun 4/110, 4/150, 4/260 and 4/280 systems upgraded with the Sun 4300 CPU board (as used in the SPARCserver 300 series) were referred to as the 4/310, 4/350, 4/360 and 4/380 respectively.
I'm a mess, I guess.
It's what I asked for, it's what I needed.
Well, you know me better than,
or at least you did then something happened.
But once again something's happened.
The confidence you held in us
the rope we almost hung ourselves with.
At times I wonder if we really took the steps
to break right through it.
I know that there were better days,
but to see the light and to feel the rays.
Life was always back and forth
and we were idling or making useless progress.
Waiting for the rain to stop.
Destination's beautiful.
Seems that I'm still waiting for the sun.
Someday will come back to us, if you're willing let it go.
Why won't you just let this be your sun?
It seems like yesterday we had the world our way.
But some say we're heading for destruction.
I'll ask you "What in the world should we do?"
This light is green our break is through.
Are we not trying or are we trying too hard?
Well, you know I never want to miss,
I hold on tight and reminisce.
But it's bittersweet to me.
When time stands still as it's trapped inside
the letterbox you gave back to me.
But I'm the one who keeps on reading.
But I'm the one who wants to let it go.
I'm the first to speak.
You're the last to know.
Another scene that we're creating,
I need to know if we're still making useless progress.
