However, old DD drives for Mac (and indeed when new MAC's access old discs) are accessed with diffeent speed per track inwards. So, one can have a standard HD drive for the Archimedes, but that will limit the reading of MAC discs to the new ones. As for HW: yes, the 177X controller found in the Archimedes can do HD. (But is it wired correctly for that - Acorn?) --Dag Haakon Myrdal ----------------------------------------------- about Norway: "Won an award, you know. Lovely crinkly edges" (Slartibartfast, THHGTTG)
