Epson PX-16/HC-160

Here's what it looks like in PX-16 mode.  Pretty much a plain-Jane DOS compatible.  Keyboard is pretty.

As usual, Epson likes to make their machines EXTREMELY flexible!  The PX-16/HC-160 is no exception.  The keyboard and the display were both changeable.  In the PX-16 configuration, the keyboard and display were conventional.  In the HC-160 configuration, it became a POS computer with a special programmable keypad.

Either way, the disk drive subsystem was removable and programs would be stored in RAM.

Swap out the display and keyboard and now you've got the HC-160.  An excellent POS terminal.  The greenish section where the keyboard is normally at is a touch screen.

Here's the docking base.  You get a floppy drive (720K) and room for a second floppy.  I checked and the circuitry isn't there for a hard drive.

Here's how things are swapped out.  Keyboard is held in place by a couple of tabs and screws.  Display is held in by a slide-in connector and a retaining screw.
