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

[Garten, David N., CTR, OSD/P&R]

ELCs are 33MHz.  Boot from anywhere (SCSI, NET).  Compare with SS2 at 40MHz.
No sbus.  Takes 4 16Meg 72 pin parity SIMMs.  2 slow ports for thingies.
Will make noise.  AUI ethernet requires a dongle to hook it to your 10BT or
10B2.  Make a fair web browser terminal or a cheap xman terminal or even a
Postscript viewer.  Way cheap at flea markets/ham shows/swap meets.  I got
the one I'm looking at out of a dumpster!  Had 64M of 16M parity SIMMs
inside, too.  

I loaded all of 2.6 running CDE on one with a 2.4G Seagate storagepack and
it doesn't make me wait too long on boot(couple minutes?).  I leave it
running round the clock.  

You can make it into a headless server with a little tweaking in the PROM.
If the darn things had a second ethernet, you could make a bitchin cheap
RISC router/firewall to DSL.  I should get it off the stand-alone drive and
serve it off another system.  Free up the drive.  Put the IPC to work with
an eth1 card as a firewall.

Anybody used SCSI to bridge a cluster?  TFTP boot a set off LINUX and
cluster a box full of em?  They are not hot.  Ought to be able to get a
bunch on a single pee-cee PS.  Now you got me thinkin!

Following up myself a bit.  It looks like it has an external scsi port
and from the faq seems to be an ELC mono monitor thing.

How does that beast compare with, say an SS1, speedwise or other
performancewise?

I am assuming it probably has 16M ram and no drive of any sort internally.
But, can it boot and run external drives, satisfactorily, or will it only
netboot?

Thanks
 
Bob
