Hit a solid milestone in my ZMachine interpreter for the Apple II. The various print opcodes now work, as demonstrated below by a test program running on my Apple IIGS that just dumps all the strings in a tiny v3 story (compiled in Inform 6).

The zork bot starts its own Bluesky root post mentioning you, so it controls the interaction settings.
Each bot reply stores the full game state in an atproto CBOR blob. So you can reply to earlier parts of the thread and branch off and try out different choices.
Bot just does zmachine(yourMove)

I built Zork in Typescript+React :~) All this talk of Zork made me want to play it again, and Microsoft released the original Zork 1, 2, and 3 source code last November so I build a node+react app that downloads the original .z3 package and runs it inside zmachine. First time using rezi for TUI

Czech (a ZMachine test story) now passes running on my Apple II ZMachine interpreter Melbor! Still plenty to do for it to be fully useable for playing games, but this is an important milestone because it means the core VM works.
