I just purchased a Mac IIsi, and I was wondering if there was going to be Virtual Memory for the 68030 (IIsi)? I remember reading sometime time ago about Apple having problems with it. Can anybody confim this, or what is the state of its release?

I tried defragging the drive...didn't help. It looks like the problem is that the IIcx doesn't have 32-bit clean roms. The reason I have only 11 Meg is that there can only be 14 Meb - 1 Meg for each NuBus card. Makes sense to me...I do have 3 NuBus cards.

I know what is wrong. You have more than one NuBus card in your IIcx. Address space includes NuBus, for which each slot "takes away" 1MB from the VM you can have. Hence, you have 2 cards in your IIcx -- video card and something else. I suppose that if you had IIci ROMs in your machine, you'd be okay -- 32-Bit "Clean," and all. While Apple refuses to comment on whether or not it is possible, I am pretty damn sure it is. Then again, Apple doesn't let you just buy ROMs... Steve Klingsporn
klingspo@mozart.cs.colostate.edu (Steve Klingsporn) (04/15/91)
Dean (and this is a correction to me too!) In 24 bit mode, you have a total of 14MB of VM possible - 1MB for every card. steve

Is this > the case or am I mistaken? Uh, well, no. VM does NOT require contiguous free space on the backing store HD. The limit is due to the cx's 24-bit ROMs. The formula (wow, higher math) is: if 24-bit, possible VM space = 14 - 1/slot occupied if 32-bit, possible VM space = 1 gigabyte, limited by page table size Limited by HD free space, of course.
