The ZX Interface 2 was a peripheral from Sinclair Research for its ZX Spectrum home computer released in September 1983. It had two joystick ports and a ROM cartridge slot, which offered instant loading times. The joystick ports were not compatible with the popular Kempston interface, and thus did not work with most Spectrum games released prior to the launch of the ZX Interface 2. In addition, the pass-through expansion bus provided was stripped, only allowing a ZX Printer to be attached. == Compatible titles == Availability of cartridge software was very limited: The cost was almost twice as much as the same game on cassette tape, and each cartridge could only hold 16 KiB, making it almost immediately obsolete as the majority of Spectrums sold were 48K-models, which the software publishers targeted. Only ten games were commercially released: # Jetpac # PSSST # Cookie # Tranz Am # Chess # Backgammon # Hungry Horace # Horace and the Spiders # Planetoids # Space Raiders Paul Farrow has demonstrated that it is possible to produce custom ROM cartridges, including the ability to exceed the 16 KiB design limitation of the ROM cartridges. 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「ZX Interface 2」の詳細全文を読む スポンサード リンク
