4am is a well-known and gifted software cracker best known for releasing detailed step-by-step instructions for cracking commercial copy-protected programs for the Apple II series, and for also producing ‘clean’ cracks, which is to say the so-called ‘warez’ were free of any vanity crack screens (where the cracker usually takes credit for their exploits).
The Internet Archive (through the efforts of digital preservationist Jason Scott) are now hosting of over 300+ of 4am’s cracks online. You can download the disk image for transfer to your Apple II, or in many cases play the disk image online through your web browser. Many of these cracks are for titles that never got much love from the pirating community, primarily educational titles.
