The PX-8 was the successor of the PX-4 and HX-20. The main improvement was a twice bigger flip-up LCD screen.
It was sold with four cartridges which could be added to the base of the unit: a BASIC Programming Language, CardBox Plus, a diary for 400 names and addresss, Calc, a spreadsheet and WordStar the well known word processor. A double 5.25" floppy drive was available, and an Epson developed stand alone 3.5" floppy drive.
The PX-8 was designed to be compatible with CP/M programs but these may need some modifications due to the display system. Actually, 8 lines of 80 characters were shown at any one time, but the display could be scrolled through up to 48 lines.
It may also act as a terminal for other computers.
The PX-8 was sold as HC-88 in Japan and Geneva in the USA.
