That brings to mind a surprise acquisition I got recently from a mixed lot
on eBay: it's an original silver case CoCo 1 with fairly low serial number,
but decked out with ECB 1.1, full 64KB, and a CoCo 3 keyboard.  Were the
CoCo 3 keyboards available to the public before the actual release of the
CoCo 3?
