I've run blockland0002 on a Windows 98 computer but I don't remember the specs. It actually ran quite well, but I couldn't load any saves because the processor apparently wasn't fast enough to load any bricks.
The weakest computer I've run Blockland on with specs I remember is:
2.1 GHz processor
256 MB RAM
GeForce FX 5200 128MB VRAM
mehh try running everquest on a school comp than come back.
the computers at my ex-school were running @ 3ghz with like 2gb ram. never found out the graphics card thought
The computers in the CAD room at my school have Quadro FX 540 cards, which according to
the wikipedia article uses the same chip as the
GeForce 6600
