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 NV-RAM. 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.
