Parity Modes

Strict parity enforcement and monitor-only mode

Switching

Hardware DIP plus jumper matrix for deterministic layout

Timing Control

Wait-state presets for weak chipset implementations

Diagnostics Tooling

DOS burn-in suite with map integrity reports

Target Systems

8088, V20, 286, 386SX hybrid benches
