This desktop computer, now sitting idle in the closet of my home office, has not been powered on for ten years. The last time I turned it on was back in 2005, just to check if it would still boot up. At that time, it struggled to start, which wasn't surprising given its age.

The internal battery, responsible for maintaining the system's BIOS settings, has long since expired, rendering the computer unable to remember basic configurations without a recharge or replacement. Furthermore, I lack an LCD monitor to connect to it, although I still possess a keyboard along with several SCSI cables that I've kept over the years.

I'm quite uncertain about what to do with this relic from the past. My most recent interaction with this machine involved backing up the entire hard drive to a CD. This was a strategic move, ensuring that I could still access the files if the need ever arose. However, with technology racing forward, the practicality of revisiting this old system diminishes daily.

The computer's chassis is dusty, and its once vibrant hardware components are now relics of a bygone era of computing. There's a nostalgic part of me that wants to preserve it for its historical value, perhaps hoping to one day to reboot it to remember System 7.

This old system, with its 3.5 floppy drive and the unique hum of its internal fan, represents not just technology but a personal journey through the evolution of personal computing. It's a piece of history, both personal and technological, that I'm reluctant to part with, even though it no longer serves a practical purpose.
