Deep Dive: CTS Flow Control in the Serial/Modem System
Why you can't just shovel bytes through a virtual modem—RTS/CTS backpressure, buffer gates, and the timing budget that makes dial-up feel real.

Deep Dive: The Z-Machine Interpreter
Building a Z-Machine transpiler in Rust—opcode decoding, Z-strings, branch offsets, and the constraints that make Infocom's bytecode tick.
Z-Machine Foundations and Storage Sync
Pushing the Z-Machine interpreter forward with decoder work, text handling, and SAVE/RESTORE—plus content-addressable storage with S3 sync.
The Dungeon Gets Real
Transforming a dungeon crawler demo into a persistent roguelike with progression, daily challenges, and meta-unlocks—all in one session.
Emulation Milestones and TypeScript Migration
Intel 8088 demos, Zig-based 6502 experiments, and migrating the frontend to TypeScript for better type safety.
Deep Dive: PETSCII and the VIC-II Text Adapter
Translating PETSCII screen memory into ANSI terminal output—character maps, colour translation, and the minimal contract a terminal-based VIC‑II can keep.
Big Repo Restructure and Backend Migration
Splitting the repository into clear domains—cores, languages, assemblers, BIOS—and making future work less of a guessing game.
Build System Groundwork and Modem Plumbing
Tightening the build pipeline for modem-core WASM, dynamic backend loading, and making the modem behave like a real modem.
Deep Dive: Bell 212A and V.32bis Handshakes
When 300 baud isn't enough—simulating faster modem handshakes with phase modulation, training sweeps, and the controlled chaos of negotiation audio.
Deep Dive: Bell 103 Audio Modem and FSK Implementation
Implementing the 1962 modem standard that made 300 baud dialup possible—FSK modulation, Goertzel demodulation, and the two-band trick that keeps full‑duplex honest.
A Small Day That Mattered
Fixing CRT modem and BBS bugs—the quiet foundation work that keeps a larger project from getting weird later.
