Goldstar 3DO Console w/ 9 Games (3DO)

The 3DO Interactive Multiplayer, often called the 3DO, is a home video game console platform developed by The 3DO Company. Conceived by entrepreneur and Electronic Arts founder Trip Hawkins, the 3DO was not a console manufactured by the company itself, but a series of specifications, originally designed by Dave Needle and R. J. Mical of New Technologies Group, that could be licensed by third parties. Panasonicproduced the first models in 1993, and further renditions of the hardware were released in 1994 by GoldStar (now LG Corp) and in 1995 by Sanyo.

Technical specifications

Processor

• 32-bit RISC CPU @ 12.5 MHz (ARM60) – using VY86C060-20FC / VY86C06020FC-2 (native stock speed of 20FC chips is @ 20 MHz.)
• Custom math co-processor (it does not use the stock ARM FPA unit.)
• 32 KB SRAM

Display

• Resolution 640×480 (interpolated), 320×240 (actual) 60 Hz for NTSC version, and 768×576 (interpolated), 384×288 (actual) 50 Hz for PAL version with either 16-bit palettized color (from 24-bit) or 24-bit truecolor.
• Two video co-processors capable of producing 9–16 million pixels per second (36–64 megapix/s interpolated), distorted, scaled, rotated and texture mapped.

System board

• 50 MB/s bus speed (synchronous 32-bit @20 MHz bus)
• 36 DMA channels
• 2 MB of main RAM
• 1 MB of VRAM
• 2 expansion ports

Sound

• 16-bit stereo sound
• Stereo CDDA playback.
• 44.1 kHz sound sampling rate
• Supports 4-Channel Dolby Surround sound
• Custom 20-bit digital signal processor (DSP) – 20-bit accumulator with 16-bit parameter registers for extended precision, embedded in the CLIO chip.
• 13 DMA channels of digital input, to be sampled, and distorted by the DSP.

Media

• Double-speed (depending on manufacturer) 300 kB/s data transfer CD-ROM drive with 32 KB RAM buffer
• Multitasking 32-bit operating system

Connectivity

Audio and video

• RF switch An RF connector can be used with older TVs that lack direct video inputs. The 3DO output is compatible with most existing video console switches, including those made for the NES/SNES, Sega Master System/Genesis, & NEC Turbo Grafix RF. This provides a relatively low quality but universally compatible video signal.
• Composite RCA The 3DO features standard composite video and audio ports (yellow/red/white RCA connectors) that are compatible with off the shelf cables also used on VHS players and certain other video devices and games consoles, as well as older computer video monitors.
• S-Video Except for the Goldstar GDO-101M model, the 3DO also offers an S-Video connector for enhanced picture quality on more advanced televisions.

Power

All 3DO consoles have integrated power supplies. Some models (Panasonic 3DO FZ-1, Sanyo TRY 3DO, and Goldstar 3DO) have hardwired power cords, others (Panasonic 3DO FZ-10) use an IEC 60320 C7 "figure 8" power cord. All North American model specifications are AC 120V 60 Hz 30W.

Basic accessories

Most 3DO systems shipped with a standard controller, as well as A/V and power cables. The 3DO controllers were unique in that the system base unit contained only one controller port and the controllers could be physically daisy chained together via a port on the back of each controller. Up to eight controllers could be linked together in this fashion. All controllers for each 3DO console are compatible with one another.

In addition, standard 3DO controllers released with the Panasonic FZ-1 also contained a headphone jack and volume control for silent play. The GoldStar (LG) model also included a controller with this feature.

Third party controllers were produced by a number of companies including Logitech. World International Trading Corporation also released an adapter that allows Super NES controllers to be used with the 3DO.
