Zellyn Hunter c65d7b9ee2 audit: combine two print mechanisms: smaller code 
The first old way was to JSR and get the value from the stack, with
string directly following. The second old way was to put strings in
their own area, and explicitly load the address of each string. The
new way combines the two: put the strings in their own area, and JSR
to a three-byte prefix of each string that just JSR's to the print
routine. The print routine pulls the string address from the stack,
and pushes nothing back, so the final JSR returns to the code that
wanted to print.

Apple II Audit

This repository contains 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 OpenEmulator: I may alternate adding tests here and features there.
