The black thing at the bottom left of the PD cycler (pictured in previous post) is a SmartMedia memory card. It allows the cycler to record data each session, which I then bring to the PD nurse so they can have a log of my treatment. The card is basically a large SD card (47mm x 35mm). The only other one I’ve seen was a 16MB card I bought for my (very) old Rio PMP300 MP3 player.
