[SunRescue] What exactly is a Sun 4/25 ?

[Hatle, Steven J.]

It's probably either an ELC or an SLC. Call it a mono monitor with either a
SS1 (SLC) or SS2 (ELC) built in to the back. If there's a door you can pop
off to slide the motherboard out of the back, it's an ELC. If you have to
remove the rear cover to get the MB out, it's an SLC.

ELC's take the same memory as IPX's. SLC's take "regular" Sun RAM.

The problem with these is that the monitor was on as long as the workstation
was on, so they've degraded with time. You can fix them by replacing caps
and other components, but taking them apart is a bitch. You had to run with
external disk to be standalone, but lots of folks either ran them diskless,
or as X-terminals. You can put either MB in either chassis, so if you have
an SLC with a good monitor, and an ELC with a crappy one, you can put the
ELC MB in the SLC and get a decent machine.

On the sunhelp.org webpage, there is a link to a guy who will tell you how
to extract the motherboard connector and wire up a PC powersupply to run the
thing standalone as a headless workstation.

Otherwise, they're pretty vanilla Sun.

I ran across a Sun 4/25 in surplus, today.  What exactly is the critter?
It looks like a monitor with a card cage thingie on the back.

What potential has such a beastie?

Thanks

Bob
