The 286 chip in the T3100 series was smaller than the regular 286 chip (IIRC). The "fun" part about it was that it just dropped into the socked (loosely), and was held in place by the heatsink that snapped on top [one of Toshiba's *many* bad designs). If the computer would get bumped suddenly, or if the chip would move due to expansion and contraction of the chip from heat, it would need to reseated. There was also VERY little airflow in those machines. The power supply has a 1 1/2" fan, and the hard drive and floppy drive were directly in front of the internal air vents, basically blocking the already limited (because of fan size) airflow. The HD controller was also buried under the hot power supply. The controller would heat up, and the P/S would heat up, causing the HD controller to blow (don't know if toshiba did this on purpose...). The HD's, if you can find one are around $150 for a 20 meg. I don't know the cost of the controllers, because I sold the thing for parts before I even thought about looking in to it. -- -Jason (roblwill(a)usaor.net) ICQ#-1730318 PS>> when the P/S starts blowing out air about as hot as a hair dryer set on "low" (about an hour and a half), you better turn it off an let it cool down for a bit (or just put it on ice). ---------- <classiccmp(a)u.washington.edu> one of the
