Gebaut hat sie Multitech aus Taiwan, die Firma, die sich 1987 in Acer umbenannt hat. F\u00fcr den Disketten-Teil sitzen ein Rockwell R6765P (\u00b5PD765-kompatibel) und ein SMC FDC9216 als Datenseparator drauf, f\u00fcr COM2 ein National INS8250 und f\u00fcr die Uhr ein MM58167 mit Pufferbatterie. Damit r\u00fcstete man einen PC oder XT in einem Slot mit Floppy, Modemanschluss und einer Uhr aus, die auch nach dem Ausschalten weiterl\u00e4uft. Mehr als 360 KB bzw. 720 KB schafft der 250-kbit\/s-Controller aber nicht.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Was ist ein Preview?<\/strong> Hier zeige ich kurz Hardware, die ich entdeckt, aber noch nicht genauer angeschaut habe. So behalte ich den \u00dcberblick und ihr seht schon vorab, was kommt. Sobald ich dazu komme, ersetzt ein ausf\u00fchrlicher Beitrag das Preview.
