Not interesting to you, but other people may differ! A cross-compiler targeting the 6502 is still interesting to some. As the article notes, these compiler techniques weren’t invented in the 70s because computers weren’t powerful enough to make good use of them. What’s wrong with exploring what the original hardware is capable of when freed from those restrictions?
It is my understanding the the GEOS system was developed on a more powerful machine than the C64/Atari computers it was used on. This let then have the entire code in memory and then processed for common functions. They could not do this on the the 64K-8 bit computers at the time.
There's nothing "wrong" with it. I'm just saying that if I'm going to read an article about fun 6502 activities, I want to see it hosted on an Apple II. If I want to read about compiler techniques, I'd prefer to see it targetting a more orthogonal (or less weird, anyway) architecture.
Okay, here's an article about calculating e to 116,000 digits on an Apple ][: <https://archive.org/download/Apple_2_Woz_e_Calc_1981/Apple_2...> (warning, PDF!). I found it interesting to read, even though I never owned an Apple ][, nor did I ever own a 6502-based computer (well, except for the Atari 2600). I was, however, able to apply the techniques to computers I did own (6809 and 8088 based).
