+* Apple II Audit
+
+This repository contain routines to audit Apple II computers (II, II+,
+IIe, IIc), providing information about hardware, ROM versions, RAM
+configuration, and behavior.
+
+Eventually, it should comprise an emulator test suite, enabling
+emulator writers to systematically identify and eliminate perceptible
+differences from real hardware. If a difference visible to code can be
+found, a test should be added to this suite.
+
+** Status
+
+I'm just getting started, currently working on:
+
+- experimenting with toolchains for automation
+- preliminary floating-bus vsync examples
+- sha1sum assembly code
+
+This test suite is a step on the way to implementing Apple IIe
+(enhanced) support in [[http://openemulatorproject.github.io/][OpenEmulator]]: I may alternate adding tests here
+and features there.
