@grishka There were 3 types of CDs: system software (the production OS, in all the languages), SDKs and I think tools? Can’t recall the last one. They would cycle by them sending one of them each month, so every 3 months you got everything updated. The 3 boxes there are just the OS, I threw away most of the SDKs and tools. The one on bottom right is a rare one with a multimedia demo of Copland. I think it had live action video of people walking around the Copland UI pointing out new features.
@grishka Oh I just remembered, the third CD was not tools (that was part of the SDKs) but documentation, of course. 😄
