Document the second machine and the Sirius Joyport New Machines page: choosing a machine, what a II Plus actually differs in (NMOS CPU, no auxiliary bank, one character set, colour burst never inhibited, slot 0 and the language card), what survives a switch, the ROMs it needs and why a machine without them is listed but unavailable, and how a profile describes one. Input Devices gains the game port — Apple joystick or Sirius Joyport — with the annunciator table the Joyport multiplexes through, the active-low switches, two-controller handling, and the reset window that stops its idle-high lines reading as held Apple keys on a //e. Its paste section was still describing the old JavaScript-driven paste; it now describes the type-ahead buffer in the core and why the gaps between characters exist. Expansion Slots gains the II Plus layout and the per-machine storage. Architecture Overview gains the machine profile layer. Printers gains the font editor. Home and Getting Started point at all of it.
