We've seen oscilloscopes repurposed as clocks and MAME machines, but we hardly ever see the pendulum swing in the opposite direction. The iMSO-104, however, actually turns your iPad, iPhone, or iPod touch into an oscilloscope display. Using a Cypress Semiconductor system on a chip, the iMSO-104 touts a 5MHz bandwidth and as much as 12 megasamples per second, and connects to your device by way of the dock connector -- according to its maker, it's also the world's smallest and most portable oscilloscope. That's all well and good, but what we really want to know is, does it support Tennis for Two? The iMSO-104 is now available for pre-order for $300, but if you're itching to see the thing in action, you can download the corresponding app today and give it a test drive. Full PR after the break.
