With its top off, it can be seen that the HP-85 has a clean and simple layout.
On the left is the monitor and display circuitry, on the right is the thermal
printer and tape storage mechanism. The main motherboard is beneath the
keyboard, shown here folded up. Except for the eight memory chips, all of
the chips are custom HP designed.
