I know. Thank you for the invitation. Which I decline. After all 95 % of the 
code is from Vassily and Dan.

I added one percent to make Hobbes run on a little Endian architecture.

The remaining four percent went to the AltoFileStream. Remember the problems I 
had with the natural numbers starting with one instead of zero?

Those four percent went in because I naively assumed that the image is storing 
the snapshot onto the alto disk. So I modified Hobbes to read the snapshot from 
an alto file stream instead of from a standard file stream. 

But when I finished the AltoFileStream I learned that the image does not at all 
store the snapshot file. This would be the job of the VM. (primitive 97). Which 
makes the AltoFileStream an exercise as instructive as useless.

Probably I won't need to change Hobbes any further for my master task, which is 
studying the Blue Book and implementing an ST-80 VM on top of Unix and X-Window. 
(Don't hold your breath as I am really slow and I have no time schedule.) The 
Hobbes Emulator was helpful especially in finding out about the file format of 
the ST-80-V2-image. See

	http://www.ba-stuttgart.de/~helbig/st80/ImageFormat.txt

By now I am looking forward to some further docs regarding the image file format 
which Luc and Mario promised.

I do not object to someone storing it into the Squeak source repository, as long 
as Vassili's license is observed, someone is going to maintain it -- and someone 
is not me :-).

Thank you all for your support.

Greetings,
Wolfgang
