==Hardware specifications==
[[File:Commodore-dtv-pcb.jpg|thumb|Commodore DTV PCB.]]
* Core circuitry
** [[Application-specific integrated circuit|ASIC]] running at 32&nbsp;MHz internally, implementing [[MOS Technology 6510|6510 CPU]], [[MOS Technology VIC-II|VIC-II]], [[MOS Technology 6581|SID]], [[MOS Technology CIA|CIA]], and PLA
* Casing/Connectors
** integrated in a [[joystick]] (as if connected to port 2 of a real C64)
** five additional buttons (acting like keys)
** running from batteries only (four [[AA battery|AA batteries]])
** [[Composite video]], [[monaural]] audio ([[RCA connector]]s)
** looks similar to a ''Competition Pro'' joystick
* Graphics
** [[NTSC]] (DTV2 and later: [[NTSC]]/[[PAL]] on chip, only [[PAL]] wired in end-market devices)
** reprogrammable palette with 4 [[bit]]s of luma and 4 [[bit]]s of chroma
** DTV2 and later: [[Packed pixel|"chunky"]] 256 color mode, additional [[blitter]] for fast image transformation
* Sound
** no support for [[MOS Technology 6581|SID]] [[Electronic filter|filters]]
** DTV2 and later: 8 bit digital sound, additional options for [[Synthesizer#ADSR_envelope|envelope]] generators
* Memory
** DTV1: 128 [[Kilobyte|KB]] [[random-access memory|RAM]], 2 [[Megabyte|MB]] [[read-only memory|ROM]]
** DTV2 and later: 2 [[Megabyte|MB]] [[random-access memory|RAM]], 2 [[Megabyte|MB]] [[flash memory]]
** [[Direct memory access|DMA]] engine for RAM/RAM and ROM/RAM transfers
** DTV2 and later: additional RAM access using bank switching and [[blitter]]
* CPU
** implementing a 6510 at 1&nbsp;MHz
** DTV2 and later: Enhanced CPU (fast/burst mode, additional registers and opcodes, support for illegal ops of the 6510)
