Sun SparcStation 4.
This SparcStation 4 has a 110MHz processor. Originally it
was one of the apache web-servers here, but it's now one of the DNS
servers for the internal network.
It's due to be replaced soon by a faster, more recent machine.
One with more memory and more hard-disc capacity. This system has been
used here for the last three years or so, and now requires a replacement
The NV-Ram chips on these, and other sun systems have a finite
life-span. (usually 8-12 years) They are however quite easy to replace
and re-program. I make a note of the Ethernet address, HostID and the
Serial Number inside the system just in case I need them at a later date!
Here is a picture of the system in the "sparc-rack" between a
pair of SparcStation 20 systems.
