The System 24 used two Motorola 68000 processors at 10 MHz. One was for input/output, while the other was used by the game. The board holds 1360 kB of RAM and 256 kB of ROM. It was the first Sega arcade system that required a medium resolution arcade monitor. The color palette was 4352 selectable from 32 768. The system could support up to 2048 sprites on-screen at once.
Sound was driven by a YM2151 at 4 MHz; it was capable of delivering 8 channels of FM sound in addition to a DAC used for sound effects and speech synthesis. Early System 24s loaded their program from floppy disks. Games could also use hardware ROM boards to store games. No matter which storage device was used, a special security chip was required for each game an operator wanted to play
