Double post, but I recently got a job lot of six laptops for £12 posted (thanks to a Nectar voucher). Two of them are Core Duo/C2D era ones, so probably of no interest here. However, these are the other ones:

This is a Pico N340S8 - a rebadged Samsung VM8000 or something along those lines. No idea who Pico are, and can't really find anything on them on the web. It's fitted with a full desktop 1 GHz PIII Coppermine with a 133 MHz FSB, and a pretty standard SiS 630E chipset. It's missing the battery, but otherwise it works perfectly; I have ordered a replacement screen due to there being some thunderbugs inside it. The desktop PIII runs cooler in this laptop than the laptop equivalents did, as long as you don't block the fan underneath (although the fan does run constantly)! Something else worthy of note is the fact you can use Tulatin CPUs with this system if you find one of the slightly different Tulatin-spec coolers.

Compaq Evo N1015v; it has an Athlon XP 2000+ CPU and an ATI/ALi chipset combination. The battery is dead but it otherwise seems to work fine; haven't set it up yet as I need the HDD caddy, otherwise the HDD flops out of its home dangerously.

Toshiba Satellite Pro 460CDX. It has a 166 MHz Pentium MMX CPU, but I have no idea about the chipset. It is missing a battery and HDD caddy (standard IDE connector seems to be built in at the back), and although it powers fine when no HDD is fitted, fitting one produces an orange blinking power light for some reason - any ideas?

HP Omnibook 2000CT. I believe it uses a 133 MHz Pentium MMX CPU, but I've not yet tested it due to not having a charger with the correct polarity. It's missing the battery but is otherwise basically complete, bar the lack of a HDD (as for all of the systems).
