I had a 486 sx 33 back in 1993 it cost over £1000 I think.
That was with 4mb of Ram, a whopping 250mb hdd, no hdd, no sound card, no cdrom drive and dos 6.2 and windows 3.1
Ok I have an Escom leaflet here for some reason, prices end Jan 1996
A dx2 66i lowest cost was £479
This was at the end of hte 486 era, as most of the computers are Pentiums at over £1000,
