I do not own a T1000SE, but I have owned and/or peeked inside 3 different Toshiba laptops (1000, 1100, 1200HB), and I have generally found that ALL of the chips are soldered... even the BIOS! I know this because I wanted to add a "no slot clock" to my T1100 (a clock which piggybacks on any ROM or RAM chip in the computer) and there wasn't a single place I could put it. In any event, even if it is socket, this is of course a SURMOUNTABLE obstacle. It's a little bit risky, but if you have a bit of electronics assembly experience it should be doable. I suspect that the biggest issue you should consider is whether there is a CMOS version of the V30 available. If not, then the non-CMOS V30 you add will add a significant power drain to the system. Will the system still run on battery? Maybe, I'd think. On AC? Probably, I'd think..
