@pleia2@floss.social I've spent very little time on mainframes. On midrange I remember how i5/OS (now IBM i, formerly OS/400), challenged my firmly-held ideas about terminals (no glass teletype!), filesystems (wait, the database goes all the way down?) and so on. I worked with it long enough to get somewhat comfortable though (F3 F3 F3...) #ibmi

@lopta@mastodon.social I had to laugh at "the database goes all the way down" because it's such a great way of putting it 😂 (And sorry to be That Guy, but i5/OS technically ran on midrange servers that were Power-based, they may have looked like washing machines, but mainframes were a lot bigger 😅 Even today, IBM Power servers can be shipped as blades, and the smallest IBM Z mainframe is 20U and requires a specific lift to install it in the rack).
