I have a question for all of you System 7 guru's out there. If a Mac Plus was equiped with a 68030 board, would you be able to use VM beyond the 4 meg limit of the Mac Pluses ROM, or would that limit still be in effect?

This is indeed what the 7.0b1 release notes indicated. However, last week I contacted the Apple Developer Hotline and asked this question. While they indicated that they could not be absolutely sure that System 7's virtual memory would work on any given machine with Compact Mac ROMs, their engineers were working on making it as compatible as possible in later Beta releases, and they suggested that they'd do everything they could to make VM work on upgraded Plus machines. Don't give up hope just yet, it's still a way to go until 7.0 goes final. -- Mark Wilkins -- ******* "Freedom is a road seldom traveled by the multitude!" ********** *-----------------------------------------------------------------------------* * Mark R.

This is not out of spite, but because they utilize ROM routines that do not appear in the Plus and SE and Portable (don't know about the Classic). Presumably they could stick these routines in the System and have them loaded into RAM to override the ROM versions but the last I read (end of '90) they said they didn't want to do this for some reason (maybe not enough demand or too much hard work). maynard Handley

Huh, what would be the limiting factor? An 030 is an 030, and a PMMU is a PMMU isn't it.....what else would VM need?
