about more than 5 years now. I bought it used on ebay for 1 Euro.
Do modern Linux kernels still support the architecture, or are you just planning on running it in a configuration "that works" forever?
From the POV of software, it's an x86, not some different architecture. That's the whole point. However, most distributions have stopped supporting x86 (32-bit) and only support AMD64 ("x64", heh).
Ah, yes, I am stupid. Carry on.
No problem...in the future you can change to OpenBSD or NetBSD, they will support x86 'forever'
