- My son has a Mac IIsi which aborts when an application finds it has used up
- its allotted memory space and needs a little more - for instance MS Word
- 5.0 with a longish document will blow up when saving or printing although
- it was perfectly happy when the file was opened. He has been able to get
- around this by giving the applications more memory through the Get Info
- dialog, but it continues to catch him on occassion and he loses data he has
- entered. I never have had this problem on our old Mac 128, or SE at home or
- my IIfx at work. Is there something flaky with the IIsi ROMs? If so, is
- there an INIT or something that can get around it? The machine is
- configured with 5MB of memory, the NuBus extender/Math Coprocessor option,
- System 7.0.1 with System 7 Tuner 1.1.1.

- No. The problem is that the MacOS hasn't gone to a virtual
- address space model. Each app allocates all the memory it will
- ever use at startup. If it needs more then it is SOL. Some
- applications need more memory on color screens, certainly
- you can be able to read in a document but not be able to
- print because the application can't allocate the print
- buffer.
