The 286 chip in the T3100 series was smaller than the

(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
from overheating, and making it seem like the heads in the HD were stuck
(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.
Oh I know the type your talking about, square 286 clamped in with pressure
contacts on all four sides. The last one I saw like that was in a Delta Gold I
had over 10 years ago. It had the white thermal compound on it to the heat sink
cover but of course that unit had more than enough air flow being a desktop
case, unless you got sloppy and let the ribbon cables block the air. I've only
worked on 2 T3100's and that was external work so I can't attest to what may be
inside.
So the hard drives are a special type huh?
