It is a "customized" version of Aladin on floppy disk. The only version I could find was in German, so I translated it in English and tweaked it to make it boot an English version of Macos 6. Still a work in progress...

Not sure if that counts for #MARCHintosh, but I'm running System 6 on my Atari ST, and I'm loving it !

Stewart Cheifet Obituary December 28, 2025 - Goldsteins Funeral View Stewart Cheifet's obituary, find service dates, and sign the guestbook.

Aw man 😞 Rest in peace Mr Cheifet, host of Computer Chronicles: obits.goldsteinsfuneral.com/stewart-chei...

What a legend. His work in both presenting and preserving the early days of computer history has been (and will continue to be) deeply appreciated! My condolences to his family and friends.
