I have a tower with a 1.13GHz Pentium III, 1GB RAM, a 40GB hard drive, DVD-ROM & 3.5″ floppy drive. I booted it up with no issues to the original install of Windows 2000 Pro. Is it still possible to use this as a daily machine if I needed to, and if so, where could I find software for it?
Yes, although security would be a potential nightmare if connected to the internet. You would need old (very old) versions of current software – some would still be available, for example Microsoft supply truely ancient versions of office as part of MSDN subscriptions.
