Imagine a totally portable computer
that slips into your briefcase, incorporating
an LCD screen, lull typewriter keyboard,
printer and microcassette,
and runs on its own power supply for use anywhere.
We did.
Extraordinary product.
Exceptional quality.
Taking the computer a step further.
A computer small enough to fit into a briefcase yet with full size
typewriter keyboard, LCD Virtual Screen, printer and microcassette facility
actually built in.
Improbable. Until today.
The HX-20.
The most complete
portable computer
available today.
Functions fantastic.
The HX-20 is a real computer, not a
gimmicky toy. Or an extension of your calculator.
Or just another desk top computer. It is a precision
machine with 16k RAM which is optionally
expandable to 32k and 32k ROM expandable to
54k, RS-232C and serial interfaces.
The full size ASCII typewriter keyboard
and five programmable keys brings ten
separate program functions to your fingertips. "
The HX-20 can run on its own power
supply for over 50 hours which can be
easily recharged overnight, and has the
ability to retain its memory in RAM even
when switched off.
The HX-20's LCD Screen is unique,
keeping you in the picture by showing any
20 characters by 4 lines at a time. You can,
therefore, carry out word processing or data entry
as if you are using a large screen.
Upper and lower case letters,
numerals, punctuation marks and
graphics are easily read by simply
adjusting the viewing angle.
Virtual Screen keeps you
in the picture.
A built-in 24 column dot matrix impact microprinter offers 42 LPM in a
crisp, precise 5 x 7 matrix for perfect hard copies on plain paper. Every time.
And there's more.
.Bit addressable
graphics allow you to design your own
characters for full graphic capability,
a cartridge ribbon, full ASCII character
set including £ sign and enough
international symbols for
reproducing most Western languages.
Print out. Built in.
Add-on capability.
Choose from a wide range of peripherals. Barcode readers, audio
cassette for loading and saving programs, microcassette
and ROM cartridges, and the world famous Epson
dot matrix computer printers for quality output
. .
.to name just a few.
Via acoustic couplers
this superb machine
can also be linked
through the telephone to
other computers.
The HX-20 uses a full extended version of Microsoft BASIC, with a
24 hour clock, date and alarm, string functions, and music generation. The
interface options (with RS-232C and serial interfaces as standard) include a
standard cassette, a ROM cartridge, plus a system bus that allows you to expand
the RAM and ROM capabilities.
Software and the hard facts.
The HX-20 is light and totally portable for writing programs and
manipulating data
virtually anywhere. (Just four nickel-cadmium
batteries and a low power all-CMOS memory gives you a reliable
power source during your travels.)
Back at the office you can dump your data or programs onto a
cassette or into your main computer system.
Portability lor Programability. Anywhere.
A computer coming from Epson has got to be good. After all we

1961. Just take a look at our impressive track record with the hugely
