Names are adapted to DOS 8.3 file names, PETSCII adaptions of core.fth are reverted (DOS uses ASCII), the input test is disabled, since no way was yet found to inject keystrokes into dosbox. And some tweaks were applied to ans-shim.fth and the golden files to make the first tests (preliminary & core) to pass.
