AppleScript strange error

[feeef]

I have tried to do some scripting with applescript on my 9500 (System 7.6.1) and I am always having the same error. This is a strange one and it is always coming back when I try to run a script (even the most simple script).

Has anyone ever had this error? Is it something that wasn't installed correctly on my system?

Does this error happen with other applications?

As I remember, you do not assign Finder as an application, but do an exit or quit to go to it.

This script is generated by the recording button and just going to the finder. It works well on Mac OS 8.1.

I tried different scrips and I always get an error. However, when a script is pre-compiled, everything works well. It is just the compiler that fails here 

Maybe something is messed up in my system... I will try to do a fresh install of the same system on another drive and see if it works ok on that one.

I tried to do a fresh install of 7.6.1 and had the same error. I couldn't even compile the default example scripts from the install.

I tried to do a fresh install from the 9500 CD install (7.5.2), I also tried to do a minimal system install with just applescript... I always got the same error when I try to compile a script from the script editor.

Does anyone have a 9500 running system 7 to see if everything works?

I was thinking that AppleScript on system 7 is not PowerPC native and the 68 emulator fails somewhere on my machine...

FYI, this Mac had a G4 700MHz upgrade and now I is running on a G3 500MHz (which handles my SATA card correctly). It has the same behaviour with both upgrades. I have a 604e 233MHz card so I should try with this one at some point to see if the problem comes from the processor...

if the 68k emulator was the problem, you'd be bombing VERY early, as System 7 is mostly 68k code

So I don't understand at all where this is from

It looks like a software problem but only with this Mac and with System 7 (all of them)...  :-/

I think it's the CPU - can you remove the accelerator and try without?

Well, I have tried 100 different things with no success, and at some point I removed some ram sticks, re-installed the system and it works now!

I think I had some bad RAM sticks so I will try to get some new ones. I think OWC still sells those 128MB for quite cheap.

How much RAM can system 7 handle? Can it go to 1.5GB ?

 

[Elfen]

What ever Apple has crippled the 9600 to handle RAM is the amount you have to play with. The system as far as I know can handle as much RAM as you can throw at it. The more you throw at it, the happier it will be.

Thanks Elfen, I may go for the 12 sticks then!

I come back to this post as buying new RAM sticks brought back the issue.
 
I have made some investigations, I tried 2 different 9500 motherboards, I tried many different memory sticks and it looks like the applescript engine on system 7 bugs when there is more than 512MB of RAM in any case.
 
The problem is that each time I made it bug with too much RAM, even after removing the excess RAM I had to re-install the system to make it work again.
 
Everything works fine under Mac OS 8 and 9 so it is something to do with 7. (7.5 and 7.6 have the same result)
 
There may be a fix or something I missed here because the 9500 and the 9600 officially supported more than 512MB of RAM and both shipped with system 7.

It seems I found a solution to that so I should be able to use the 1.5GB of RAM of my 9500 with 7.6. 

I just replaced the AppleScript and AppleScript lib extensions with those coming from a Mac OS 8.1 install. It looks like it is working well so far.
