I decided my backup CDs from 2002 may be nearing EOL and pulled the data off them, only to realize that back then I thought postscript files were future-proof. Turns out ps support was removed from MacOS in Sonoma https://eclecticlight.co/2023/09/25/postscripts-sudden-death-in-sonoma/ So now I'm working through how to convert to PDF either on MacOS https://eclecticlight.co/2023/09/27/how-to-convert-postscript-and-eps-files-in-sonoma-in-a-vm-apple-silicon/ or maybe I'll just spin up a raspi just to get this done.
