Description

Ini adalah skema Nintendo Famicom KW/Clone. Awalnya ini skema Dendy Junior dan Megawalkman JNR-01. Desain awal saya dapatkan dari sini: https://github.com/mleonid2000/dendy_junior_remastered

Untuk blok Video saya menggunakan transistor, versi Megawalkman. Tapi untuk blok Clock saya mengadopsi dual clock milik Dendy Junior, PAL dan NTSC. Skema diatas dimungkinkan untuk mengubahnya menjadi NES(Nintendo Entertainment System) Clone. Cukup gunakan 72 Cartridge Slot, ganti CPU dengan UA6527 dan ganti PPU dengan UA6528. Seting Clock pada NTSC dan sedikit perubahan jalur.

For the Video block I use a transistor, the Megawalkman version. But for the Clock block I adopted Dendy Junior, PAL and NTSC's dual clock. The above scheme is possible to change it to NES / Nintendo Entertainment System Clone. Just use 72 Cartridge Slots, replace the CPU with UA6527 and replace PPU with UA6528. Clock settings on NTSC and slight changes in path.
