Dieser Computer nutzte einen TMS9900-Prozessor von Texas Instruments mit einer Taktfrequenz von 3 MHz. Er verf\u00fcgte \u00fcber einen echten 16-Bit-Bus, weshalb sehr schnelle Speicherchips, n\u00e4mlich statisches RAM, zum Einsatz kamen. Aufgrund der hohen Kosten von statischem RAM verwendeten die Ingenieure jedoch nur 256 Byte SRAM f\u00fcr den schnellen Zugriff. Die 16 kB normalen dynamischen 8-Bit-RAMs, die haupts\u00e4chlich f\u00fcr Grafikzwecke gedacht waren, liefen \u00fcber einen 8-Bit-Bus und waren deutlich langsamer.<br>Auch beim ROM gab es eine Besonderheit: Der TI99 verf\u00fcgte \u00fcber 8 kB eigenes ROM und zus\u00e4tzlich \u00fcber das seriell erh\u00e4ltliche \u201eGROM\u201c \u2013 Graphics ROM.<br>In den USA wurde der TI99 als Heimcomputer und Spielkonsole beliebt, da viele Spiele auf ROM-Cartridges, auch Module genannt, ver\u00f6ffentlicht wurden. Er konnte mit einem modularen Rack f\u00fcr mehrere Cartridges, einem Diskettenlaufwerk oder einer Speichererweiterung ausgestattet werden. In Europa war er aufgrund strenger Exportgesetze und dem Mangel an Anwendungen f\u00fcr Systeme mit so geringem Speicher eher selten anzutreffen.<\/p>\n\n\n\n<table id=\"tablepress-256\"
