a) WordPerfect 2.1e fixes the problem of not being able to save over an existing file. Presumably other vendor's upgrades/fixes will do the same thing. Musta been a minor toolbox interface change. b) GS/OS is now such a memory hog I'm thinking about adding some more. 1.25 meg ain't enough, I guess. When I do so I'm thinking about getting a battery backed up kind so I can keep my most used stuff in quasi-ROM (that's what I call it.) Question -- is there any way of putting only the most frequently used parts of the system into that RAM/ROM while the rest stays on the hard drive? How would I even know what "most frequently used" is? What stays memory resident between applications? (once you load a tools does it need to be reloaded, for instance?) What, if anything, stays resident when you run P8 and a P8 application? c) In the same spirit, sort of. The original P16 was a shell than ran on top of ProDos8. Will there ever be a P8 that runs as a shell on top of GS/OS rather than as a separate program? What about BASIC.SYSTEM for that matter -- it is a shell/interface between the Microsoft Basic in ROM and P8 -- could it not instead be an interface to GS/OS (which now that I think about it would almost eliminate the need for P8 ... oops, I guess not, you still have to service old 6502 machine language programs that are calling the P8 MLI.) d) is there now under Sysdisk 5.0 (I'm sorry, I dont' know what version of GS/OS it is that is on it) any way of reconfiguring RAM5 without cycling the cpu power? I thought I had figured out how to use the shutdown menu item under 4.0 (although never consistently) but now that's gone. 'nuff for now TMPLee@Dockmaster.ncsc.mil

I dunno what you mean by cycle the CPU power (I think that's what you said), but I do know you can hit control-open-apple-option-reset, and the new settings will take effect. This eliminated shutting the entire machine off, as I've seen many people do. Osiris

Nope. (Although to some extent the system *already* does this [in regular RAM, not with your RAMdisk]. When toolsets and drivers are no longer needed, for example, they are marked "purgable." When they're needed again, they are often still in memory & don't need to be reloaded from disk.) >How would I even know what "most >frequently used" is? What stays memory resident between applications? >(once you load a tools does it need to be reloaded, for instance?) >What, if anything, stays resident when you run P8 and a P8 application? Under 5.0, most of GS/OS & its drivers stay in memory (although they aren't being used) while you're in P8. >c) In the same spirit, sort of. The original P16 was a shell than ran >on top of ProDos8. Will there ever be a P8 that runs as a shell on top >of GS/OS rather than as a separate program? That's a very interesting question, but the answer is probably "never." There was a discussion of this idea many months ago on AppleLink--PE, and it turns out that there are some hefty technical problems with letting the system work that way. The toughest problem I remember at the moment is that P8 applications are allowed to do direct access to devices (SmartPort calls, ProDOS block-level calls), and GS/OS explicitly forbids this. >What about BASIC.SYSTEM for >that matter -- it is a shell/interface between the Microsoft Basic in >ROM and P8 -- could it not instead be an interface to GS/OS (which now >that I think about it would almost eliminate the need for P8 ... oops, >I guess not, you still have to service old 6502 machine language >programs that are calling the P8 MLI.) Also interesting, but Applesoft is pretty much permanently limited to running in bank 0 (only 64K, and a fair amount of it is already taken up by GS/OS). >d) is there now under Sysdisk 5.0 (I'm sorry, I dont' know what version >of GS/OS it is that is on it) any way of reconfiguring RAM5 without >cycling the cpu power?

First, you can always resize RAM5 by starting a self-test and then hitting Apple-Ctrl-Reset. System Software 5.0 doesn't provide a new way to resize it with ROM 01, but there are 3 ways to do it with ROM 3: 1. Apple-Shift-Ctrl-Reset 2. Choose "Resize after Reset" in the RAM Disk section of the Control Panel CDA (text). This is a "one time" option...it doesn't stay chosen. 3. Check the "Resize after reset" check box in the System Software 5.0 "RAM" CDev. --Dave Lyons, Apple Computer, Inc. | DAL Systems AppleLink--Apple Edition: DAVE.LYONS | P.O.
