The SVI-728 was the first home computer from Spectravideo that complied fully with the MSX home computer specification. It was introduced in 1985. The design is virtually identical to that of the earlier SV-328, which did not comply fully with the MSX standard. The SVI-738 is a portable version of this computer. ==Technical specifications== ;Microprocessor * Zilog Z80A with a clockspeed of 3.56 MHz. ;Memory *ROM: 32 KB *RAM: 64 KB (expandable to 256 KB) *VRAM: 16 KB ;Video *Graphical processor: Texas Instruments TMS9918A/TMS9929 (NTSC/PAL) : *Graphical resolution: 256 x 192 pixels : *text modes: 40 characters x 24 lines and 32 characters x 24 lines : *colors: 16 : *sprites: 32 ;Sound *General Instrument AY-3-8910-soundchip : *3 sound channels : *1 noise channels : *1 envelope controller ;Connectors *1 data recorder/Cassette deck *2 joysticks *1 cartridge *1 Super Expander *1 disk station 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「SVI-728」の詳細全文を読む スポンサード リンク
