In 1982, two years before the PX-8, Epson released their HX-20 portable computer, what many
consider the first so-called notebook computer ever.
Now, in 1984, we have the PX-8 "Geneva", a similar but very different notebook computer system. While the earlier
HX-20 ran BASIC, the PX-8 is one of the only handheld computer systems which runs CP/M. The PX-8 can
also run BASIC, as it also exists in ROM.
This particular PX-8 has the optional memory expansion unit attached to the bottom of the system.
It adds an additional 128K of RAM which can be used as a RAM-disk.
Seen below is the optional external floppy disk drive PF-10. Like the PX-8, it also can be run on batteries.
There is no room in this system for the micro-printer of the HX-20, but the micro-cassette drive is
still present for data storage and retrieval. It can even play taped material such as voice or
music through the PX-8's speaker.
Small ROM modules can be installed in the bottom of the unit which can including Wordstar, Supercalc, dBase II,
and others. These ROM appear as drives to the operating system, and are accessed as such.
