[comp.sys.mac.system] Old II with 6.0.5 & MF --> crashes; any clues?

robertj@Autodesk.COM (Young Rob Jellinghaus) (03/15/91)

I have a five-year-old Mac II that just recently got 6 more meg and
a 68851 (thanks to Autodesk).  I've been trying to get MPW 3.1 up on
it.  I used to be running Finder 6.1, System 6.0.2, and whatever
version of Multifinder went with those two, and MPW would lock up when
it tried to start a tool under Multifinder.  Not acceptable.

So I decided to move to Finder 6.1.5 and System 6.0.5 and all the
stuff that goes with them.  I used Installer to install the "System
software for Macintosh II", and started having the following problem:

Set Startup is Multifinder Only, and the Mac is booting.  It comes
up into the Finder OK.  But after maybe three to five mouse clicks
(opening windows, scroll bars, whatever), the Finder suddenly chokes
and restarts itself (all windows go away, the menu bar clears, and
then the windows reappear just as if I'd just booted the Mac).  If
I play a bit more, the Finder often gets into an infinite restart
loop--the menubar appears, then disappears, then appears, etc.--it
never even makes it to displaying any windows.

This happens without any INITs or CDEVs except the ones the Installer
added.  When I put MacsBug 6.1 in the System Folder and start the Mac
up, it tells me that the Finder is getting a bus error, like so:

    Bus error at 4080E29E	_HandleZone+0022
    *MOVE.L (A1),D2 	    	| 2411

I tried just plain dragging the System, Finder, and Multifinder from
the 6.0.5 release disks, without using the Installer, but the same
thing happens.

PLEASE, can anyone help with this?  My Mac is almost useless until I
get this problem fixed!  I sure hope the fickle net comes through on
this one....
