Creating Schematics for Old Computer Circuitry: CAD Freeware

Well, I seriously doubt I'd end up want to CAD an entire PSU, but habing to struggle making an ASCII art schematic this morning got me thinking about CAD freeware again. I work for an architectural firm, and have AutoCAD installed on my workstation, but I don't have a symbol library of electronic parts, so I haven't bothered trying to use it for electronics. I do have PADS*PCB, which is available as either a commercial product or as crippleware (something like 60 components). I was just starting to get pretty gppd with it when I had to shelve the project I was working on for work that had regular paychecks. Does anyone know of/use a freeware CAD program for producing moderately-complex schematics? Something a bit less than what you'd need to create the typical modern PC motherboard (although VLSI seems to have taken some of the complexity load off the motherboards)? I really don't even need PCB component layout or autorouting, just a nice schematic program. tia, -doug quebbeman
