[Welcome to December Days, where I natter on about things organized around a theme (sometimes very loosely), one a day, for 31 days. This year, we're taking a look back at some touchpoints along the way of my journey with computing and computing devices.]
( The Atari 2600 )
- CPU: 1.19 MHz MOS Technology 6507
- Audio + Video processor: Television Interface Adapter (TIA)
- Output: B/W or color TV picture and sound signal through RF modulator. 2 channels of 1-bit monaural sound with 4-bit volume control.
- RAM (within a MOS Technology RIOT chip): 128 bytes (additional RAM may be included in the game cartridges)
- ROM (game cartridges): 4 kB maximum capacity (64 kB with bank switching)
- Input (controlled by MOS RIOT): Two screwless DE-9[a] controller ports, for single-button joysticks, paddles, trackballs, driving controllers, 12-key keyboard controllers (0–9, #, and *), and third party controllers with additional functions. Six switches (original version): Power on/off, TV signal (B/W or Color), Difficulty for each player (called A and B), Select, and Reset. Except for the power switch, games could (and did) assign other meanings to the switches. On later models, the difficulty switches were miniaturized and moved to the back of the unit.
