I used this for ccd imaging, then used it in recording studio. Recently bought a really nice desk computer. This is 600 mhz 183 ram. really nice little computer for imaging. has USB port/external monitor/printer/ps2 ports. No serial port. for $650 Ill let this external cd burner go with it. its a lite on, really fast, nice. Burn images on the spot. Nice set up! Have ME on it currently. touch pad cursor control. Modem only works with ME.. Which is currently working, but I also bought for it a modem card for running other op system.
