Memory Management Memory management includes the Memory Manager, virtual memory and other operating system services. The following changes to memory management have been implemented: * On PowerPC computers, the Modern Memory Manager is always active and the classic 68K Memory Manager is not available. * System 7.6 only supports 32-bit addressing. 24-bit addressing is no longer supported. If the computer's Parameter RAM (PRAM) settings indicate that the machine is in 24-bit mode at system startup, the PRAM is set to 32-bit addressing and the computer is restarted. * Since 24-bit mode is no longer supported, most checks for 24-bit mode and calls to SwapMMU have been removed from the virtual memory routines, thus reducing the calling overhead. * Virtual memory page fault execution times have been shortened by removing 24-bit runtime code. * The Modern Memory Manager on PowerPC computers now communicates directly with the Virtual Memory Manager to greatly reduce page fault disk accesses to the VM backing store file. * Allocating and deallocating temporary memory is much faster. ... System 7.6 indeed does not support 24-bit addressing at all, and given that 24-bit code has been *removed*, attempting to hack around this limitation would appear to be a recipe for disaster. chazl 05.12.97 ------------------------------ Date: Tue, 13 May 1997 08:42:23 -0500 (CDT) From: "Mark E. Ingram" Subject: [Q] Apple Two-Page Video Card Mac Experts: I would very much appreciate hearing from some of you "old heads" on a video question. I am trying to get a Mac IIcx to run System software later than 7.0.1 (preferably 7.5.5), but everything I have tried so far is unstable (including various flavors of 7.1, 7.5.3, etc.). If the debugger is present, the most frequent crash is: "The ROM symbol file could not be read due to an OS or memory error. NMI" I *suspect* that this is more of a generic than an actual, specific problem, but really don't know. Anyway, I talked to SOS-APPL about this, and in passing they mentioned that "some third-party video cards had problems with System software later than 7.0.1." When I told them I had an *Apple*-branded "Two-Page Monochrome Video Card," which shows up in a profiling program as a "Mac II WorkStation Video Card: 1152 x 870, 1 bit," driving an *Apple* 21-inch (two-page) monochrome monitor, they didn't have much else to say. Is the video card contributing to this problem? (I don't have another Nu-Bus card with which I can test a different, smaller monitor, and the IIcx does not have the IIci-style built-in video support.) Are there any special "tricks" to get later System versions to run on the IIcx? BTW, the IIcx is working incredibly well as an AppleShare 3.03 and At Ease for Work Groups server, but later System software would enable quite a number of newer software packages to be run on the computer (the ANAT tools Network Assistant, and User and Groups Manager; and OT 1.1.2 and AppleShare IP 5.0 client, to name just a few). One other question: This video card has eight empty slots for what appear to be a type of SIPP RAM chip. Would filling these (assuming any could even be found) make any difference in the *speed* of screen-redraws, rather than just add to the bit depth capabilities of the monitor? Best regards, Mark E.

Specifically, when I use extension version 5.0.1 both Mac and Windows CD-ROMs work fine, but when I try to copy something from a Mac CD-ROM to my hard drive my Mac locks up. When I use extension 5.1.1 I can copy from the Mac CD-ROM to my disk without problem, but then Windows 3.1 won't recognize that there's a Windows CD-ROM in the drive. I installed the latest CD-ROM software (5.3.2) recently, and again, Windows can't find the CD-ROM. In the past I recall a statement that the version to use is 5.1.6, but when I looked at the Apple software site the only version available then was 5.1.7. Now the only version available is 5.3.2. So, any advice on where I can find 5.1.6, or what other steps I need to take, will be greatly appreciated.

Does any one recall where to find the script or how to write it?

The Performa capture video great. The movies are smoothly played back. However, the 6500/250 hesitates every second or two during both capture and playback. It is as if I was transformed back to the days of slow CD players. The behavior is what I would guess is appropriate for a non-AV rated hard drive. Anyone have this problem with a 6500/250 or other video capture Mac? 6500/250 configuration 250 Mhz 603e.

We were approached by a client wanting to achieve this (to comply with corporate environmental policy) and we wrote a small package called "DoubleSider" which uses AppleScript and PreFab player to print even or odd pages for any application, either currently running or not. Its a bit fiddley to get going (requires the right AppleScript extensions) and it requires PreFab Player (commercial) but if anyone is interested, please shout and we'll negotiate with our client!

I've been supplied a PowerBook 180c at work. It apparently hasn't been used much, and they reformatted the hard drive and put 7.1 and ClarisWorks 3 on it fresh. All seemed fine till I started installing the other software I would need...ethernet, network extensions, etc. Much of this software was on DSDD disks. The PowerBook refuses to read any DSDD 3.5 disk I have tried, even though these same disks work fine in other macs. If you put a DSDD disk in, it says it can't recognize the disk format and wants to format the disk. If you click on OK, it then formats the DSDD disk to 1.3 megabytes! It will then uses the disk fine...but of course no other mac reads those disks (I'm not sure how stable these incorretly formatted disks might be over time, either...) Anyone have ideas on what might be wrong (sensor for the second hole in DSHD disks shorted out so it thinks all disks are DSHD?) here or how to fix it (cheaply)? Would the floppy drive from a PowerBook 145 fit and work in the PowerBook 180c? Or are they different drives? All ideas appreciated. Thanks in advance as usual. ------------------------------ Date: Mon, 12 May 1997 12:37:53 -0600 From: "Wayne C. Morris" Subject: Printing every other page-Is it possible?

That's usually left up to the application, not the printer driver. Mac word processors and page layout programs have had this capability for years. It's usually a set of radio buttons in the Print... dialog box. You didn't say what application you're using, but if it doesn't have this option, you're probably using either a really old program or a no-frills one. I checked a number of Mac programs. WriteNow 3.0, Nisus Writer 4.1.6, and PageMaker 5.0 all have this feature. So does the demo version of Mariner Write. SimpleText does not, which is no surprise since it falls in the no-frills category. Word 5.0 does not, but it's both old and Microsoft. ------------------------------ Date: Mon, 12 May 1997 20:11:17 +0000 From: Christopher Adams Subject: SE RAM resistors "Hofferth, Dan" asked: >A friend at work has a Mac SE that he is attempting to >boost from 1 to 4MB. [snip] >However, if the Mac >sits idle for more than a couple of minutes, it crashes. A couple of extracts that may be relevant from "The Mac SE Support Pages" at: "Note also that SIMMs in the same row must be of the same speed (150ns or faster)." "Later model SEs have a jumper clip instead of resistors. It's labelled 'J16' and will have the words 'RAM size 2/4M 1M' printed on the board. If you remove the jumper, you can address 4mb. If you put the jumper to the left, you can address 2mb. If you put the jumper on the right, you can address 1mb." ----- Chris Adams, Birmingham, UK. cadams@edprint.demon.co.uk ------------------------------ Date: Tue, 13 May 1997 07:20:06 +0200 From: "McCloskey, Patrick" Subject: Waiting for Apple Video System I ordered the Apple Video System from MacMall in February. Since then they have sent me several letters to tell me they have not received it from the manufacturer yet. Does anyone know what the story is? Is anyone else still waiting?
