回复主题: 猪头大餐：街机主板大巡礼.续 3D的魅力
作者:快乐猪头
62.4、MODEL 3
活跃时间：1996-1999
这是君临天下的王者基板MODEL2的接班人，同样由世嘉与洛克希德·马丁公司联合研发，着重强化了阴影描绘和纹理映射机能，其画面效果在当时可谓是惊为天人！这也是世嘉、乃至整个街机游戏历史上最为超越时代的一次演出。MODEL2的大部分名作都在MODEL3上推出了续篇，可惜由于价格昂贵，当时在国内只有一线城市才有可能在街机厅见到这些作品。
MODEL 3 STEP 1.0
硬件规格：
Main CPU : 32bits RISC PowerPC 603 66Mhz
Graphics Chip : 2 x Lockheed Martin Real3D/PRO-1000
Sound CPU : 16bits 68EC000 11.3Mhz
Sound chip : Yamaha SCSP/YMF-292F/"LAKE" FH1 128-step DSP x 2, MIDI interface, 16 bits 64 voices 4 channel, maximum of 16.5 Mbytes ROM, 64 PCM channels
Audio RAM : 1meg (8 megabits, 512K per SCSP chip)
Main Memory : 8 Mbytes 66mhz Ram, graphic ROM maximum of 64 Mbytes, backup RAM 64 Kbytes
Video resolution : 24KHz 496(H)x384(V) one or two plane 24khz, It uses the VGA pinout however. And, the voltage levels of the video output is at VGA levels (.7vdc Peak to Peak)
Scroll Window : two plane (24KHz/two plane mode), 16 colours/32,768 1024 palette x 2 bank, 256/32,768 64 palette x 2 bank
Geometrizer : 1,000,100 polygons/s for square polys, 2,000,200 for Triangle polys
Renderer : 60,000,000 pixels/s
Video : Full Color Texture Mapping, Tri-Linear Interpolation, Micro Texture, Shading High-Specula Gouraud Shading , Fix Shading, Flat Shading, Texture & Edge Multi Layered Anti-Allasing, Lighting Effects, Parallel Light, 4 Spot Light, Pin Spot Light, Special Effect Zoning-Fog, 32 Levels of Translucency.
Board composition : CPU + VIDEO + ROM boards
Others : 10mbs Connection, calendar IC
OPTIONAL MPEG SOUND BOARD DESCRIPTION
Hardware : DSB1
CPU : Z80
Sound Chip : NEC uD65654GF102
Notes : Can play back music in stereo or can stream mono music from left and right channels seperately. Hardware : DSB2
CPU : 68k
Sound Chip : NEC uD65654GF102
Notes : Can play back music in stereo or can stream mono music from left and right channels seperately.
Board picture : Full board
High Quality Board pictures : Main Board - Main Board 2 - Main Board 3
Notes : With Model 3, Sega decided to design a new system from the ground up. Again, going with the company that they had formed a good relationship with, now named Lockheed Martin's Real3D division (Martin Marietta had now merged with Lockheed to form Lockheed Martin and Real3D was created from the combined 3D graphics resources of MM and Lockheed's own). They were brought in to assist in developing the brand new graphics subsystem, which ended up being the twin Real3D/Pro-1000 chipset, stunningly powerful for their time.
Emulators : MAME (Preliminary)
Boat Race GP

曾经展出过的赛艇游戏，但最终未能面市
Virtua Fighter 3 1996.9 AM2
10579511057952
世嘉着力打造的王牌大作《VR战士3》，最终BOSS水银战士变形的特效甚至可以媲美大片《终结者2》，当时被玩家称为“花300日元看一下画面也值”。地形要素、侧闪、肢体动作强制中断等设计可谓是铃木裕追求真实格斗效果的极致体现。世嘉当时公布了本作移植SS的计划，在“圣诞大餐”《VR战士对格斗之蛇》中也加入了本作的部分要素，但最终还是未能实现
Virtua Fighter 3 Team Battle 1997.10 AM2

《VR战士3组对战》，1998.11.27移植到DC作为首发游戏。
Get Bass / Sega Bass Fishing 1997.12 AM1
10579551057956
《钓鲈鱼》，世嘉AM1研打造、MODEL3基板，效果自然是秒杀了同期ST-V基板的作品。1999.4.1移植DC
