You plug that PCI card into a PC, which in turn connects via SCSI type connector and cable into a giant box which contains the PS hardware with the extra RAM and faster CPU. Inside the box should be a series of EPROM slots, although I have not seen inside personally. The software I believe installs on Windows 2000/XP.
