Lightly-used Toshiba Satellite A105 laptop with:
1.6 GHz Celeron-M CPU, 1.5 GB RAM, 80 GB HDD, WiFi and ethernet (modem, too), 4 USB ports, CD & DVD RW drive. I've used this computer to control a rig before, using a USB-serial dongle (not included).
Freshly-wiped, has the virgin Windows XP load and software that came with it. With the system disc, Office registration card (we never activated it) and power supply. Battery was replaced 2 yrs ago with 4-hour battery and it is good.
Got my XYL a Window 7 box, hoping it will be harder for her to get viruses:)
$175 + shipping. I will reply from a different email address than what you send to with the link here. My real email is via the ARRL alias if you wish to skip that step.
