The laptop works and actually has a usable battery, but it's not exactly a speed demon and doesn't really have the memory capacity to run XP. Could be ubuntu'd, we shall see. It's not exactly a priority.
I have yet to try the GX150, which I suspect is another deadite, and the 110 which is almost prehistoric in Dell terms, and the three Industrial PCs which are... well, they are actually single-board computers on a passive PCI/ISA backplane. I'm guessing they may be either pentium 2's or possibly Xeons of that era; these were freakin' expensive machines from the year 2000, with (gasp) 7.5G hard drives in each one. Funny enough, at least one of them is chock full of PCI-bus A/D cards and I actually know how to read and write to these beasties.
If the boards actually work as single-board computers, they might be fun to play with for little midget controllers. Hell, the price was right, I think my bid for these was 50 cents each. Even if they're complete junk inside, the heavy-duty rack-mount cases are pretty spiffy.
I also have a couple of machines from the last auction up and running: a 2300 PowerEdge server (running ubuntu server, but can run XP), and a couple more laptops. One of the laptops needs to be repaired with a steady soldering hand and some time and would be a pretty decent machine (Sony Vaio), another laptop is running ubuntu, and another laptop horks trying to install.
There was another Dell machine in the first batch that I sent to Barb. She's quite happy with it, but her needs aren't exactly those of a power-user.
