3do M2



Development kits and prototypes of the machine became very valuable pieces among collectors. M2’s technology was integrated in the multimedia players FZ-21S and FZ-35S, both released in 1998.[citation needed] Both products were aimed at professionals working in medicine, architecture and sales, not home users. The M2 also became a short-lived arcade board by Konami. As games ran straight from the CD-ROM drive, it suffered from long load times and a high failure rate, so only five games were developed for it.

The M2 was reportedly several times (2–3) more powerful than the Nintendo 64 in terms of polygon graphics capabilities and slightly more powerful than the 3Dfx Voodoo Graphics (Voodoo1) accelerator chipset for PC cards.[citation needed] Matsushita claimed it was almost on par with Sega’s Lockheed Martin-designed Model 3 arcade board.[citation needed] The Model 3 was approximately 10 times more powerful than the Nintendo 64.[citation needed] In a 1998 interview by Next Generation magazine, WARP’s Kenji Eno said that Sega’s Dreamcast was about three to four times more powerful than M2.[citation needed]

The M2 technology was later used in automated teller machines, and in Japan in coffee vending machines.[citation needed]

In the late 1990s and from 2000 on, the system was also sold in the interactive kiosk market. In 2000, PlanetWeb, Inc. began offering software to allow the M2 to be used as an Internet appliance.[4]


In 2010 the only completed M2 game, IMSA Racing, was made available to the public.[3
