E > EPSON  > PX 4 / HC 40   


Epson
PX 4 / HC 40

This computer is the successor of the HX-20.

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, a lot of things or ... nothing.

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

The PX-4 was logically followed by the PX-8.
