Ditto in several models of Zenith laptops as well that used
26 pin JVC type HD's. I REALLY loathe those!
When some finds like this, usually HD is blown (that is from my
experience).

Best solution is find a old scsi bios based ISA card and a low power
scsi HD avgerage 3 to 8W. Find a way to adapt it in. On Zenith
series, the 8 bit isa slot on back is missing a 5V power, I hooked
from 5V source from inside which works.

This is really dodgy hack but that is real start. I still have the
ZWL-193-xx laptop with nice grey-blue screen. Later on when thigns
is slow, will trace out that pinouts on that motherboard side 2
connectors using the ISA pins as reference and some tracing.

T1600 is nice BUT uses EGA LCD (wierd, imho should be VGA at that
point). Did Toshiba sold those T1600 series with either JVC 26pin
and real IDE (better!) by different "controller boards"?

My suggestion to your 3200e, pull that whole socket and that sick
CPU and install a 68pin PLCC and find a HARRIS or any 80C286 PLCC
and plug that in. That CPU is no good after long time of use at
hotter temperatures and beginning to fail plus that socket is
getting bad as you have seen.

My choice: T5200 (cached 386 with vga plasma, prolly use real IDE
port) or other T4400 using 486 CPU. What's your pick?
