New display-board-1408.md: pin-level definition of the board's outputs (8 multiplexed hex digits via ICM7228B, isolated LPT LED monitor block, no readback path) and, from the firmware disassembly, everything the RIO puts on it: F0 boot banner, F1 test-mode banner (keypad sequence A-9-E enters, D exits), and the sub-test displays — five live encoder-count readouts, button test with input index, two lamp patterns, keypad test.

RIOJoy
Modern Windows 10/11 interface between the cockpit RIO (Remote Input/Output) board and Windows, as a virtual joystick / keyboard / mouse — the successor to the legacy vJoy-based app, with no vJoy dependency.
The RIO has 72 digital inputs and outputs (lighted buttons) and 5 analog axes (joystick X/Y, throttle, left pedal, right pedal), connected over RS-232 at 9600 8N1. RIOJoy exposes these to games that don't natively know about the cockpit hardware, with per-game profiles. (The native games — Firestorm, Red Planet — talk to the RIO directly and do not use this app.)

Building
Requires the .NET SDK (8.0 or newer) plus the .NET Framework 4.8
targeting/developer pack, on Windows. The apps target .NET Framework 4.8,
which is in-box on every Windows 10/11 machine — so deployed builds are
framework-dependent and need no runtime install on the target. The driver
builds separately with the WDK (see driver/README.md).
dotnet build RioJoy.sln -c Release
dotnet test RioJoy.sln
Status
Phases 1–5 are implemented and tested (241 unit tests). The RioGamepad virtual
HID driver is built (KMDF + VHF), test-signed, installed, and verified: it
enumerates in joy.cpl, and the C# HID feeder (DeviceIoControl →
RioGamepad.sys) drives its axes, buttons, and hat end-to-end (see
tools/RioJoySmokeTest). The C# side covers the serial
- RIO protocol core, input mapping + output routing, axis calibration + plasma
display, the tray app + profiles (JSON config,
RIO.iniimporter, three-state auto-switch), and the HID report packer that matches the driver's wire format. Remaining work is on-cabinet (real RIO serial/axis/plasma/auto-switch verification) plus packaging (Phase 6) and the profile editor + overlay generator (Phase 7). Seedocs/PLAN.mdfor the full roadmap.
