I chose x86 because I wanted to try the os in my ancient PCs like a Celeron 333MHz. And articles I was reading at the start was for 32bit.
That makes sense. It's been so long since I've seen a 32bit x86 (apart from single board industrial type stuff) - that I didn't really consider anyone would keep one around... Then again, we do have our old commodore vic 20 in a cupboard somewhere...
