Here are my latest purchases:

The Toshiba T4600 I think I mentioned earlier. After having the PSU board recapped, it now fires up fine, but still needs some attention; I need to sort some of the cabling layout inside, and the floppy drive doesn't work (it just makes a horrible whirring noise, almost like a belt has come off the motor if that's how it works), so I'll have to load MS-DOS and Windows 3.11 on another system. I'll use a 512MB CF card with it, as the 800MB HDD it came with is also bad - as were most of the floppy disks it came with, sadly. I do have its original power brick, which works fine. it has a 486SL @ 33 MHz, a monochrome display, and 4MB of RAM.

A Powerbook G3 "Wallstreet". Don't know exactly which model this is, thanks to the smashed screen (although it is a TFT); it was sold as being a 400 MHz Pismo, which it isn't. The HDD does work and it boots up fine to Mac OS 9, but there's a login password so I haven't gotten any further yet. It does have a good battery though, and the CD drive sounds like it should be OK. Also, does anyone know what language the non-Latin characters on the keyboard are from?

An IBM ThinkPad 560X. This is an incredibly thin and light laptop - few modern ones will be lighter. It doesn't have any internal floppy or CD drive, but it works fine with the TP600 external floppy drive, and I hope the PCMCIA ports work. I had to fit a HDD (a 10GB drive), and that now shouts "OMG you have bad sectorz" at me... because I'm pretty sure the BIOS doesn't recognise anything bigger than 8GB. With a bad main battery and CMOS battery (the latter isn't even fitted right now), I can't update it, yey! Everything bar those batteries seems to work fine though, at least what I've tested so far. It has a 233MHz Pentium MMX CPU, NeoMagic MagicMedia 128XD graphics, and a 12.1" 800x600 screen.
I also bought another Satellite 460CDX for parts, although I need to find my longer screwdriver, and sadly both its CD drive and battery were stone dead (the CD drive doesn't even try and spin a disk, which I've never seen before - the light just stays on solidly).
