Collection of Commodore 64 (C64) type-in code as found in magazines like Compute! and Compute!'s Gazette.

• Focus here is on MLX 2 code from December 1985 onwards, and Automatic Proofreader 2 BASIC code from March 1986 onwards
  • MLX 2 hex format: address + 8 bytes + checksum
  • Automatic Proofreader 2 format: checkum + BASIC line
• Source code is parsed via OCR
  • First-pass OCR has many misread characters that need correction
    • OCR is parsed in a custom JavaScript program, using JS versions of the MLX 2 and Automatic Proofreader 2 checksum generators
  • Corrected OCR is used in several ways:
    • Orginal version for reference and output variants
    • MLX 2: Hex bytes only version for disassembly or conversion to valid .PRG via C64List
• Each program folder contains source and final files with load instructions
  • Load .PRG directly in IEC mode; can also wrap it in a .D64 file
    • .PRG extension can be deleted from filename
  • Tested on VICE emulator
