I'm pretty sure the handhelds were all done on 6502s, but I don't have much else to add about them. I saw them at the time, when APh was still in Glenn's living room, but didn't work on them myself. I did help build and test the "briefcase" style datawidgets that preceded the ones in a formal box. The briefcases were an off-the-shelf Samsonite model, but deep enough for the two-board stack that was the datawidget, with an open-frame power supply on the side. One of those may have accompanied the attache case you mentioned.
