Introduction

These documentations have been typed in from yellowing papers that were done with a typewriter more than a decade ago, based on personal experiments with a C64C plus 1541C setup. As such, they are, by far, not comprehensive and are only meant to be quick references around while working. This is also the reason for the documentations having been "printer optimized": tailored to make them fit onto as few papers, when printed, as possible.

The Hungarian translation of two books provided immense help with finding out how Commodore equipment works: 64 Intern (© by Data Becker GmBH, 1984; translated by Novotrade Rt., 1985) and Das Grosse Floppy Buch (© by Data Becker GmBH, 1983; translated by Novotrade Rt., 1986).

DISCLAIMER: The originals of these documentations are very old and may contain errors. While typing in, obvious errors have been corrected. However, the author assumes no responsibility for the correctness or completeness of these documentations.
