I know there was a thread on the list about the earlier models - haven't found it in the archives yet. I've the stuff from the FAQ and various resources on the IBM 5150, etc. I really need something quite quick and snappy. Can someone point me at some decent stuff or books on the hardware side: CPU modes (real and protected) Memory addressing (segments, flat) Memory holes. EMS, Extended, Expanded memory - are these relevant to elks I don't want to talk at length on this stuff (but want to learn anyway), but feel it'd be good to paint an overall picture. Paul
