I've just purchased a new workstation: Precision M6700. I would like to swap the express card reader for the old PCMCIA reader so that I may use my sound-card: an equally prehistoric Sound Blaster Audigy ZS 2 (notebook) because well, as Pa would say so often; "They just don't make things like they used to". May I do a clean swap or perhaps use an older/other model reader and keep the i/o intact ie: it will look and function factory without unsightly protrusions, wires, etc.?
