A PCMCIA Soundblaster Audigy 2ZS Notebook soundcard. 24bit/96khz, THX certified 7.1, DVD-Audio playback, optical in and out etc. Vast improvement on usual internal laptop sounds.
Has some slight damage (few chips in plastic housing), but worked when I last used it in a laptop with a PCMCIA slot. All installation CDs (but no printed manual) and wiring loom included.
As per title, this is free as I can't test it/can't be bothered selling it, but was quite expensive new and if it is of use to you, a small charitable donation to somewhere of your choice would be appreciated.
I'd like to take this off your hands to try with my Acer Laptop. Happy to donate to Cancer Research.
