A very recent issue of BYTE had an article go into (in my mind, to much) detail
on the HP-150 and the design processes behind it.

Does anyone know if the touch screen used is based on the designs by Carrol
Touch Technologies or if HP designed their own? I know that they use photo-
cells and infrared cells, but some aspects of their design seemed to be
different than the processes patented by Carrol (namely, the self-alignment
features).
