Technical Data[]
Two Motorola 68000 CPUs, one at 7.61 MHz or 7.67 MHz (PAL or NTSC) and the other at 12.5 MHz (Mega-CD mode) A Zilog Z80 A at 3.55 MHz or 3.58 MHz acts as a sound chip in Mega Drive mode and as a CPU with a Sega Master System adapter. 64 Kilobytes of RAM Backup to save game states. The screen consists of 2 scroll planes. Each tile is an 8x8 pixel square with 4 bits per pixel, each pixel can have 16 different colors.
A Texas Instruments SN76489 provides 3 channels of square wave sound and 1 of white noise and a Yamaha YM2612 FM with 6 voices and 4 operators. In Mega-CD games, these 8 channels are added to stereo Audio CDs. On the rear, 10VDC 850 mA power connector and access hatch to the battery compartment.
Capability[]
Because of the cartridge slot on the back and the front-mounted flip-top CD-ROM drive, Multi-Mega can play both Mega Drive and Mega-CD games. Unlike the portable Sega Nomad, it can only be used as a game console if an external power supply and television/monitor cables are connected. The Multi-Mega is powered by two AA batteries, which will quickly drain if high-quality batteries, such as lithium, are not used.
Sega 32x Compatibility[]
The Sega 32X accessory is not authorized for use in the United States. The 32X and Multi-Mega combo works in Europe but not in the United States. Caution must be used with the hardware to avoid dropping the unit or doing anything else that will cause the weight of the 32X to shift. Because none of the clamps included to secure the 32x with other Mega Drive / Genesis consoles are suitable for the Multi-mega, it is much more prone to breakage.
