[comp.sys.mac.apps] MY System 7 compatibility

peter@suntan.viewlogic.com (Peter Colby) (05/20/91)

	First, let me say that I got System 7 (all 8 800K images) plus
DiskCopy 4.2 plus the Compatibility stack off of ftp.apple.com Wednesday
morning. I started downloading about 7:30AM EDT and finished about 8:10.

	Because of the way I organize my HD it took me about 4 hours to
make the full (to my satisfaction) installation. I have a 4MB Mac Plus
(started as a 128K Mac in spring of '84) with a large HD divided into
10 32MB partitions with two smaller partitions using up the rest of the
space. I use Silverlining and I maintain a SEPARATE (hard) partition for
every system I run. I change systems by using Silverlining's DA to flag
the system partition I want to use as mountable on bootup (turning off
the boot mount for the other systems(s) and restarting.

	I used the custom installation to install only the Mac+ System
software plus a couple of printer drivers (Imagewriter and Laserwriter).
The installation was done onto a CLEAN 8MB partition with nothing else
mounted. Even my Plus only took about 15 minutes to complete the entire
installation procedure. What took up all the time was copying all my
INITs, CDEVs and FONTs to the new system, and setting up my Apple menu.

	So far, this is what I've discovered.

	o System 7 appears to be as fast as 6.0.5 EXCEPT I converted
	  my finder display font to Times and TrueType takes a while to
	  "type out" the Italic print for the first alias when I open a
	  window.

	o The following INIT/CDEVs do NOT appear to work.
		Magic Menu (part of StuffIt Deluxe 2.0.1)
		MasterStrokes (Function key software for the
			Datadesk 101 keyboard).

	o These INIT/CDEVs appear to work fine
		GateKeeper & GateKeepers Aid 1.2 - took a while to
			get running, I had to reboot before GateKeeper
			controls would respond in the control panel.
			I run the INITs from the Extensions folder and
			the CDEV from the Control Panel folder.
		ATM 2.0 - The INIT runs fine from the Extensions folder.
			The "CDEV" works fine (from an alias) in the
			Control Panel folder but the outline fonts and
			the driver MUST be in the System Folder.
		Moire 3.0 - Appears to work OK: File in the the extensions
			folder, alias in the control panel folder.
		ShortCut 1.5

	o Silverlining 5.25 has problems - it had the same problems on
		6.0.4, 6.0.5, worse on 6.0.7 (why I never ran 6.0.7) and
		almost unusable on 7.0 - The problem appears to be
		related to my combination of HD, System, and Silverlining
		(detailed in another post). This does NOT appear to be
		a specific System 7.0 issue.
		The Silver Volumes DA works fine.

	o The following applications appear to work OK
		Compactor 1.21
		Compactor Pro 1.30
		MacWrite II V1.1 - crashed once but that may have been related
			to the Silverlining problem.
		ResEdit 2.1 - the automatic rebuilding of the desktop on my
			applications partition gave ResEdit the InitPicker
			icon for some strange reason - only in the finder
			window, the icon display in all other case (menus
			etc) is the appropriate Jack-in-the-Box.
		StuffIt Deluxe 2.0.1
		Redux 1.62
		Alpha 3.50
		DeskZap 2.0b10 DA

	IN SUMMARY. I like System 7 a lot and would use it exclusively except
for my Silverlining problem which is forcing me back to 6.0.5 until I can
resolve it.

Silverlining 5.28 or later should be used with 7.0.

Is this also true on non-32bit ROM machines also? I'd heard that 5.28 was only
needed on the 32bit clean Macs which wanted to use 32 bit adressing because
the drivers before 5.28 were not 32 bit clean.

To the best of my knowledge this is not true. Silverlining has
supported A/UX for quite some time. 32-Bit cleanliness is a
prerequisite for an A/UX-compatible hd driver.
 
Versions of the Silverlining app prior to 5.28 didn't work properly
under 7.0; no crashes or destructive behavior, just weirdness.

A/UX doesn't use the drivers off the disk, it has it's own generic 
SCSI driver (because it has to be able to do disconnect reconnects
etc etc) 

What Silverlining does provide is the ability to create A/UX partitioned
disks 

In other words working with A/UX has nothing to do with 32-bit cleanliness
(at least as far as disk drivers are concerned).

I think that the main reason why disk drivers fail under 7.0 is not
usually because of not being 32-bit clean but instead because in order
for a driver to work under VM it must be reentrant (for example: if you
start doing a write to disk the driver might take a page fault and be called
halfway through the write to read in the data from the paging file that has
to be written out).
