I was also an "intern" of sorts for Mitch as recently as 2009 or so. I wrote the audio driver for OLPC XO 1.5 and went to Taipei to help with the bringup. I was amazed to watch Mitch using Forth to interactively tweak the DDR memory settings, find bugs in the motherboard, and find bugs in the CPU which was a godawful x86 from VIA that had seemingly only been debugged enough to boot windows :)
