2.0 ports to connect USB devices, such as mouse, keyboard, modem, printer, etc. There
are four ports on the PC99 back panel and one header on board. Please note that USB 2.0, with fancy speed up to 480Mbps, is
40 times faster than the traditional ones. Except for the speed increase, USB 2.0 supports old USB 1.0/1.1 software and
peripherals, offering impressive and even better compatibility to customers.
Note: Please note that if you would like to use
USB devices (Example: keyboard, mouse etc.)
under DOS environment, you must install driver
