I meant nothing which you have inferred from my question. I merely wanted to know if you had a specific purpose for running Adobe on your Classic. For instance, if you had all of your recipes in Adobe files and wanted to create a recipe Mac for your kitchen. Of course it would be optimal if the Classic could directly share them with your primary Mac or PC. Since they cannot, you have to translate every PDF you want to share with your Classic and sort of negates the idea of running PDFs on the Classic. Since you have to convert the PDF files anyway, why not convert them to something the Classic was better designed to handle, like text or pict?---Why would I want a Classic itself? Why would I want to run Cubase in a Classic? Why do I want to collect things? It is supposed that when you find something for collector purposes and try to find it useful, the more things you get for it (software, programs, apps...), the better it is. ... Probably this will grow up in the near future. It depends on how do I persevere on it. But if your question is....«Why would you want to load that program or do that thing in a Macintosh Classic»....why would a forum like this should exist?
I don't think anyone is saying don't try. I think we are all saying, as I have, is that there are better options depending on why or what it is you are trying to do. Your perseverance on getting Cubase to work is more about getting something designed to work on the Classic up and running several decades after the information for making it work has long since been forgotten, rather than trying to get technology from a modern Mac to run on a Classic.
I certainly am the last to discourage anyone from trying to push the limits of what an old Mac can do, as I have proposed some truly whacky ideas on this forum. But I will tell you that I have learned that it is often important to have a goal when pushing the envelope on old Macs. I am grateful for alternative solutions to the ones I present on this forum as they have saved me much grief, particularly when I did not have a definitive purpose in mind for my experiments, other than to simply see if it could be done. If in the end, your only goal is to see if you can get Adobe 1.0 to work on your Classic and convert newer PDF files to that format, then by all means let us know how that turns out! Who knows it could eventually be useful. However, I think Tom's words are apropos here, "obsessed" is the perfect word for what many of us engage in on this forum. Expanding functionality of antiquated technology in the face of difficult odds, is definitely an obsession.
