Pentium 2 300mhz includes carrying case, house charger (battery dont hold a charge for too long), external dvd-rom, ethernet card and modem. Asking $125 shipped currently running windows xp has serial and usb ports. Worked great tuning my hyundai for the longest but i've got a new one now. Its got 256mb of ram and i think its a 10 or a 20 gig hard drive... great condition only thing wrong is the latch for closing it is broken (stays closed no problem though)
