X-ray of my HP 28S. 28 kV, 63 mAs. Not sure what the large dense circular object is, but it's something that sits under the LCD. Perhaps some epoxy covering up a chip. I'll have to try another shot with higher energy x-rays.
I know IORS is today's new shiny thing, but lets not forget #ISS#SSTV. Transmit and pass windows are really bad for QTH this season, but I could grab this one from a very low-angle pass half an hour ago.
