I used MacScheme earlier, which also was a huge amount of fun - even though I did not have the extension to access the Mac Toolbox (Toolsmith, IIRC).

MCL was a whole new world then. First with Object Lisp and later with CLOS. I used MCL before it was owned by Apple - at one time it was called MACL (from a market agreement with Franz, IIRC). But later LispWorks was another step up, because it was a big grown up full extended Common Lisp with everything from the commercial UNIX workstation Lisps (like Allegro CL, Lucid CL, LispWorks): it suddenly ran on small and simple to use Apple or Windows laptops, plus it had a Cocoa port.

But, as you describe, the simplicity and integration of MCL into the early MacOS was a lot of fun and there was a lot of tinkering by users. Some friends were still using MCL years after it was obsolete...

I started with the full version of MacScheme about the same time that I started with CCL. I loved them both, and at first I liked MacScheme better because Scheme was a smaller, simpler language, and easier to learn. CCL won me over in the end because it was just so much easier to get things done.

Later on, John Ulrich, who owned Lightship Software, the publisher of MacScheme, came to work at Apple and became a friend and colleague. I continued to use MacScheme off and on for years.

I’ve happily paid for Lispworks licenses many times now, but even Lispworks isn’t a good solution for everything I want to use Lisp for. A modern version of CCL’s graphical environment would still be a nicer place for newbies to start. You could even use Lispworks to build a product like that, if the license didn’t prevent it. (Lispworks doesn’t allow their product to be used to make Lisp development systems, which is understandable. They’re a small company who don’t want to put themselves out of business by enabling a customer to give their Crown Jewels away.)

yes, building a product to include development tools (compiler, ...) of LispWorks or Allegro CL would be expensive and not really attractive. I think Franz, Inc. has such a licensing agreement for Allegro CL, but their licensing model is different anyway.

In former times there was a market for add-one GUI or IDE tools. Lucid CL made money from licensing their Lisp to other companies, which then resold those with tools added on (like the SUN Common Lisp IDE). The Action! GUI designer was available for MCL. CLIM was an add-on product. The big Expert System development environments were available as add-on products to Lisp systems.

For a commercial customer something like LispWorks or Allegro CL might still be worth it - they are technically very stable platforms.

I tried to work out a way to reimplement my old programmable WYSIWIG word-processor, Alpaca, using Lispworks, but we've been unable to reach an agreement that works for me and for Lispworks. They don't want me to make something that someone could use to compete with their product, and I don't want to make a crippled version of Alpaca.

I wrote the original Alpaca in CCL, using its Cocoa interface. I used it to write a book, and a Japanese company approached me about licensing it for a product, but I fell ill before I could do anything more with it. By the time I recovered enough to look at it again, it had bitrotted. The macOS interfaces had changed out from under it.

I imagine I could fix it up and get it going again, but I'd really like to make a version of Alpaca that works on Linux and Windows as well as macOS. The obstacle is that I need a rich-text engine that can do a good job with page layout, and I don't know whether there's a suitable one, or which Lisp (that isn't Lispworks) would be best to use with it. Qt maybe? Perhaps with ECL? I guess I'd rather use CCL or SBCL. Anybody know of a text-and-page-layout engine or collection of libraries that will work well on macOS, Linux, and Windows with CCL or SBCL?
