最近心血来潮,又重新入了台3do,以前收过台1FZ一代裸机。
重新打开这个老古董发现以下几点:
1、比较了下这个古董的16人街霸版本和土星版街机版,除了音效还发现3do版的16人街霸不是低解输出或者说是240p输出,而是差值成640p输出,虽然背景单层卷轴,但是画面显示和游戏动作流畅度来看还是非常接近街机的,土星的版音质就是街机的音质,显示上土星的16人版本被拉宽了。所以这个3DO 16人版本还是比较值得玩。
2、玩3do少不了野球拳之类的真人影像游戏,作为3do来说播片能力绝对比土星强(土星***cd卡另说)。
3、视频输出是垃圾,没有RGB直接输出,造成最高只能用S端子来接显示器。
4、读盘上来说2代版本的3do(后期翻盖版)读盘能力比手抽屉1代的强,至少我手里很多杂牌刻录碟没问题,而且2代机的光头也比较好配,某宝上就有(跟车用cd光头一样)
其他观点待续
附3do硬件配置
Technical specifications
Processor
32-bit 12.5 MHz RISC CPU (ARM60)
Custom Math co-processor (It does not use the stock ARM FPA unit.)
32kb SRAM
Panasonic FZ-1 “Clio” graphics accelerator
Panasonic FZ-1 “Madam” graphics accelerator
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 bits) or 24 bit truecolor.
Two accelerated 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 @12.5 MHz bus)
36 DMA channels
2 MB of main RAM
1 MB of VRAM
2 expansion ports
Sound
16-bit stereo sound
44.1 kHz sound sampling rate
Supports Dolby Surround sound
Custom 20-bit Digital signal processor (DSP) – 20 bit accumulator with 16-bit parameter registers for extended precision
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[edit]
Audio & Video[edit]
RF Switch An RF connector can be used on older TVs that have no RCA jacks. The 3DO is compatible with NES, SNES, Sega Masters, Sega Genesis, & NEC Turbo Grafix RF switches. This provides the lowest video quality.
Composite RCA The 3DO, just like the Amiga CD32, has standard composite video and audio (red/white/yellow RCA connector on both ends) ports that are compatible with off the shelf cables like the ones used on DVD players and other video devices.
S-Video The 3DO has an S-Video port on the back for the best possible picture quality (not on the Goldstar GDO-101M model). |
