Dang son, why you got to get into the heads of the Coleco designers. BUT, that is a darn good question, obviously they wanted internal no fuss onboard storage......data drive. Possibly if things had not gone haywire, the ADAM night have had an external dat drive. I firmly believe that almost nothing is impossible to add to the ADAM, it just takes "out of the box" thinnking and the ability to engineer and tie the hardware in with innovative software. We just don't have that level of expertise available? Or if we do, it is such a big task, nobody wants to tackle it alone.
