Instead of Ataris I am always given old PCs. This time another 486 class machine. An AMD DX4/120Mhz with 16MB RAM, 1GB HD, S3 64V+ Trio graphics card and something that seems to be a Sound Blaster compatible audio card. The motherboard has 5(!) PCI slots and 3 ISA's.
Edit: Because I was puzzled by the colour (brown) and the location of the 5th PCI slot, I must conclude that it's a VESA local bus.
