over in my country, i can get a really "CHEAP" famicom system for like US$8. comes with 1 multi-game cart, 2 jpypad, 1 lightgun, ac adaptor. just plug in power, plug av cable to tv, plug in cart, and mario plays. the console has a power-supply circuit and a single-black dot .. i guess is the famicom chip-in-1. not even a rf modulator insight.. just lines to video/audio jack. now i've seen one with KEYBOARD too!!
i wanted to mod this system so it can act like a time-controlled relay switch for my home's lightings. i've read alot about NES development, is it the same for this famicom thing?
here're somethings i need you guys to lighten me.
1. when i dump my written code to eprom/sram or whatever, the prg address starts at $8000/$c000, how do i set the NMI/IRQ vectors? 'cause i need the NMI to do real-time clock counting. 60pulses for ntsc right?
2. is it possible to wire-up some sorta latch to the address so it can control a relay?
3. possible to wire-up 8255 or some VIA(6522) or watever interface controller?
4. can this famicom system run off NiCad batteries?
i guess with proper hardware and some simple software, this $8 console can become a alarm-system too!! hehe.. with sound-generation, no need for bulky siren-circuit. just plug in a speaker(c/w amp) and whirling whole nite.
please help.. now i need to build the eprom programmer so i can test real code on the system.
bye.
