I recently purchased this Commodore 64 on eBay in a bit of Retro nostalgia. Bring on the C= hacking!
Ok, here’s the batch of parts I received from Digi-Key for my C64 DTV.
I ordered case-mount parts so I wouldn’t have to worry about making boards to mount the connectors.
CP-1060-ND – 6-Pin DIN Male Connector (Tested to fit into C64 IEC port)
CP-1260-ND – 6-Pin DIN Panel-Mount Female Socket (Mates with CP-1060-ND)
609-1524-ND – 9-Pin DSUB Male Plug with Solder Cups
CP-2960-ND – 6-Pin Mini-DIN Panel-Mount Female Socket
576K-ND – Phono Jack, Black Center, Panel Mount with Hex nut and Hex base
401-1282-ND – SPST 16A Rocker Switch (White Rocker on Black Housing)
401-1279-ND – SPDT 16A Rocker Switch (White Rocker on Black Housing)
EG2015-ND – Momentary 3A SPST Pushbutton Switch with Solder Loop Pins (Red Cap and White Stem)
SC1048-ND – 0.1″ Panel-Mount Power Jack Connector, Solder Loop Pins, with Hardware
Here is the main PCB of the C64 DTV, along with the On/Off switch and Fire buttons, which have their own PCBs.
The positioning of the PCB is, of course, upside-down and backwards, but that’s OK.
The V+ and V- wires came from the V+ and V- connectors from the battery box on the lower portion of the joystick case. There is a large version available for your viewing pleasure by clicking the link below marked “original”.

Ok, so I unscrewed it, but here’s the moment of glory!
4 screws on the bottom (Not under the rubber feet; in their own holes. Wow, this thing really WAS made for hacking) and it just pops open.
The power switch and LED just slide out of the bottom shell as one unit, the A/V cord pulls out too, and the only things left holding the bottom are the power wires. A quick zip with the desoldering iron fixed that problem.
This is my new, snazzy Commodore 64 Direct-to-TV 30-in-1-games joystick. I ran it, played some games, now it’s time to hack it up!
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. The design is similar to the Atari Classics 10-in-1 TV Game.
Tulip Computers (which had acquired the Commodore brand name in 1997) licensed the rights to Ironstone Partners, which cooperated with DC Studios, Mammoth Toys, and The Toy:Lobster Company in the development and marketing of the unit.  QVC purchased the entire first production run of 250,000 units and sold 70,000 of them the first day they were offered. Coincidentally, QVC’s West Chester, Pennsylvania Studio Park headquarters once were Commodore’s offices.
The C64DTV runs on four AA batteries. It has two fire buttons, four function buttons, and composite video and monaural audio outputs. The internal hardware is a clone of the C64 and thus has the same features and limitations, but it lacks the keyboard and I/O ports. The internal circuit board has exposed solder points for floppy-drive and keyboard ports, and detailed instructions for adding them are available.
There are two versions of the C64DTV. The first appeared in late 2004 for the American market (NTSC television type), and has these features over the original C64:
