Archiving your programs from cassette to PC

Visit http://www.mc10archive.com

For BASIC language programs use this method:

  1. CLOAD the program into the MC10 then CSAVE it directly to the PC (with the shortest possible leads), using your favourite audio capture program saving as WAV file. 44.1KHz 8Bit Mono
  2. LOAD saved file into the emulator (don’t worry about editing the WAV file)
  3. SAVE the program
  4. Use the C10TOWAV conversion tool to convert the C10 file to a WAV file

For machine language programs use this method:

  1. Use BACKUP or ID.CSAVE and CSAVE directly to the PC
  2. Use the BACKUP program loaded into the emulator following step 4 of the BASIC conversion

The saved program in WAV format can be downloaded to a real MC-10 by plugging your audio input lead into the speaker output of the pc’s sound card.
