月刊電脳倶楽部 (Gekkan Dennō Club), or in English, ‘Monthly Cyber Club‘ was a magazine for the X68000 computer that featured cover-mounted floppy disks and was published by 満開製作所 (Mankai Seisakujo). This was the same publishing house that had brought the title Oh! X (another magazine that featured a cover-mounted disk and precursor to Monthly Cyber Club) to the X6800 computer. The disks would feature a variety of material spanning both reader submissions and material gathered from the public domain, or PDD, Public Domain Document as abbreviated on the disks. Content would range from text files to FM music to CG artwork and more.
