Epson PX-4

The Epson PX-4 computer was the successor of the popular HX-20 model.

The main cosmetic difference is a wider screen that can be adjusted to the right angle. There are 2 ROM slots under the machine to implement additional ROM programs.
On the right of the LCD display can be plugged a tape-recorder, a plotter, RAM expansions etc.

A lot of peripherals were available for this little computer (see hardware page), at least in japan.

The PX-4 was later superceded by the PX-8.
