Hi guys,
I was looking at the old Squeak VMs since they're very simple and helpful to understand basic things.
I wanted to look at Squeak 2.2 image [1], but it seems the folder is corrupted. Can anyone fix it ?
I downloaded the Squeak 2.0 image instead.
I can open the Squeak 2.0 image with the Squeak 3.8.18beta1U VM, found in the 3.8 folder, source and change files work. However, I wanted to use the VMSimulator, in its class comment it is written to use this code to run it: (InterpreterSimulator new openOn: Smalltalk imageName) test But I get a SubscriptOutOfBounds error...
I am on Mac OS X.
Do you know what is wrong and how to run the VM Simulator of Squeak 2.0 or Squeak 2.2 ?
I tried other VMs and images but I was not successful...
Thanks for your help,
I CC Bert since he might know the answer to these questions.

Hi Clément,
Maybe have a look at SqueakJS (http://squeak.js.org) which can run old Squeak images as well. I find its source code quite easy to read.

Hi Clement,
Are you using the old VM code from the Squeak 2 era, or are you using current code from package 'VMMaker' to run the old image?
In recent years I have tried to keep the VMMaker package and support code healthy and up to date, but I have put no effort into the simulator, and I do not expect that it will work very well. The simulation capability in VMMaker.oscog is much superior to anything you will find in the VMMaker package. So unfortunately the simulator may not be very useful to you.
On the other hand, the actual code in the VMMaker package is relatively simple, and if you do a "VMMaker initialize" after loading it, you should be able to browse generated C code in normal browsers, which may be helpful for reviewing the code.

Sorry, please disregard, I did not read your note carefully. You clearly said that you are using the Squeak 3.8.18beta1U VM with the VM code that is in the older images.

FWIW, I've tried out the 2.8 image with the 2.4 vm, seems to work.
Is there a reason to not prefer the latest of the 2.* ?

Well I'm just trying to get an image close to Blue book specs.

Hi Cl??ment,
I guess that the earliest Squeak images would probably be closest to blue book.
I tried running Squeak1.13u.image on an interpreter VM on Linux, then opened that same image in its simulator (see attached screen capture).
I got an out of bounds error that is probably similar to what you are seeing in the Squeak 2.4 image. It is failing on the very first oop in #adjustAllOopsBy: and it seems to be going wrong when it calculates sizeBitsOf: for that oop (which is 8).
self sizeBitsOf: 8 ==> 631178496
This looks definitely wrong but I do not understand the source of the problem.
For background, here is a summary of what images can be run on an interpreter VM (but I have only done this on Linux, I am not sure if you can build the VM on OS X).

You can also use SqueakJS, although will run slower so maybe not as good for running InterpreterSimulator.
Dave
If you look at ftp://ftp.smalltalkconsulting.com/ That has the Mac compile source from 1996 thru 2010 and a squeak 1.1
I am sure there are metrowerks disk images about and on a 68K emulator you can compile the earlier VMs

Just to be clear, I can run Squeak 2 and earlier, my problem is that I cannot run the VM simulator inside it.
I have the exact same error as David T. Lewis, on multiple different VMs & images (Squeak 1.13 to Squeak 2.8).
What is the common piece between those VM and image that break the VM simulator ? Could it be related to the binary read streams ? hum...
Thanks for fixing Squeak 2.2

Hi Clément,
the earliest vm I can run on Windows(!) is 2.7
For this, I grab the windows vm, image, changes ... from http://ftp.squeak.org/2.7/ Start the vm, resize the display to make it smaller, make a snaptshot with a new name 'small.image' Now I reopen the original image and I can now load the InterpreterSimulatorLSB with that smaller image:
(InterpreterSimulatorLSB new openOn: 'small.image') test
