Can I help out? I use a 386DX/40 at home and a 486DX/25 at work. Both have 8 megs of 70ns RAM and both run OS/2 v2. I can't tell the difference speed-wise. They are about the same. BTW, both have Connor 120meg hard drives. If what I am doing required a maths co-pro, then the 486 would win by miles, but nothing I do requires a co-pro (waste of space for most people......).
