The C64 Direct-to-TV, called C64DTV for short, is a single-chip implementation of the Commodore 64 computer, contained in a joystick with 30 built-in games ([http://en.wikipedia.org/wiki/C64_Direct-to-TV C64_Direct-to-TV]). | The C64 Direct-to-TV, called C64DTV for short, is a single-chip implementation of the Commodore 64 computer, contained in a joystick with 30 built-in games ([http://en.wikipedia.org/wiki/C64_Direct-to-TV C64_Direct-to-TV]). | ||
The games are stored on a built-in 2MB flash memory. | |||
The joystick can be bought at Conrad (but I've also seen it at Zielpunkt) for ~25 Euros. | The joystick can be bought at Conrad (but I've also seen it at Zielpunkt) for ~25 Euros. | ||

Note that some soldering points are located under the rubber buttons. For flexibility, I built internal connectors to easier be able to disconnect and debug the connectors. | ||

== Power Supply == | |||
When connecting peripherals to the joystick, it will not be able to run from batteries anymore, so I'm running it from a DC power supply. Since the joystick assumes a 5V power supply, I've build a 5V voltage regulator circuit. The regulator is connected to the output of the battery pack (see picture). NB! Remove batteries before connecting external power. | |||

== TODO/ideas == | |||
* Reprogram the built-in flash memory with an updated game collection | |||
* Add a memory card reader which supports reading disk images stored on a CF/SD/XD/USB-stick/whatever memory card. | |||
