You can put up to 128 meg RAM in an SE/30 using 16meg SIMMs. Very useful website for the old Macs. http://home.earthlink.net/~gamba2/index.html If you want to run System 6 on it with more than 8 megs RAM, Connectix had some extensions for that. MAXIMA enabled it to address up to 14 megs in 24bit mode in System 7. OPTIMA/32 and OPTIMA/128 enabled 32bit mode support in System 6, for 32 and 128 meg RAM. VIRTUAL added virtual memory for System 6 and for System 7, on Macs where Apple's System 7 VM wouldn't work. VIRTUAL also used less hard drive space than Apple's VM, which uses a minimum of the physical RAM plus 1 meg. Anyone know where to download these old Connectix extensions? Connectix quit selling them shortly after the release of the IIci and System 7. Software developers quickly abandoned System 6 once System 7.0 was released. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Vintage Macs group.
