As I understand it, the 68000 based machines have a current memory limit of 9 megabytes due to the 24 bit addressing of the operating system and the number of address lines in the ZorroII buss. The rest of the 16 megabytes is divided into various blocks, each with there own specific purpose ( I/O, ROM, etc.). The A3000 having the 68030 is obviously a full 32 bit system with a cramped limit of 1.75 gigabytes :). My question(s): 1) What is the rest of the 4 gigabytes set aside for? (I'm looking for detailed info, kinda like what appeared in BYTE for the A1000) 2) Does 2.0 allow addressing this much memory? (I realize the answer is yes, but thought I should ask anyway (sp?)). ------------------------------------------------------------------------------- Andy Nagy (ptoper@asterix.gaul.csd.uwo.ca) The University of Western Ontario, London, Canada "The complexity of the application is inversely proportional to the programmer's perception of the complexity of the OS." -me
