The Epson HX-20 Screen

Introduced in 1981, the Epson HX-20 was a neat little computer in its day. It was a fairly low power consumption laptop that actually worked. It had small LCD screen, a built-in microcassette drive and a built-in thermal printer. The full-size keyboard was very nice and the machine garnered a pretty good following.

Thank you to Roy Strutt who donated a brand new expansion unit for my HX-20 and shipped it all the way from Scotland!

I have a mint HX-20 with power supply and carrying case. It looks brand new. It was purchased for my sister who could not speak, however, she passed away before she was able to use it. It was new when when she received it in the hospital and after her death in 2006 I have had it ever since, it is a one owner machine that has been never been used. If you are interested in buying it let me know.

Seek any software for HX-20: casettes, prints, sounds (mp3 also, 128K, not less), floppy-ROM, etc. Thanks for all.

I've written a small program to read and write HX- 20 tapes (or communicate with an HX-20 directly using an audio cable) from a PC soundcard.

The program is in a very preliminary state, and currently runs under Linux. It can be downloaded at http://hxtape.sourceforge.net/

My wish is that people will share their HX-20 software they salvage using HXTape by uploading them to the wiki at https://sourceforge.net/apps/mediawiki/hxtape/inde x.php?title=BASIC_programs

Hello there,

I'm looking for an Epson HX-20 (also other small computers); I'm a casual collector, that hopes to one day create a small computer museum. For me, it's all about having fun, and carefully preserving the legacy of portable computing. Also, I might be willing to do a trade and/or cash combo. Thanks...

The HX-20 uses a package of 4 C-size Ni-cads. The originals gave 1.1AH, but because of improvements in technology, they are now 1.6AH or more. Get 4 with solder-tabs and some really wide heat- shrink tubing and you'll have no problems making your own pack.

The printer was not a thermal one, but a real mechanical dot matrix (needle) printer, which used ink ribbons.

I have two HX-20s atm, one with a tape unit and expansion and one with neither. They are currently sitting in storage about 600miles away so I can't check them over but iirc one may have a fscked battery.

I'm willing to sell or maybe give them away if someone will give them a good home.

I'm based in Leicester in the UK.

Feel free to drop me a line at mike at technomonk dot com if interested.

Despite its 6Mhz CPU (really that fast?) its BASIC was much slower than BASIC-interpreters (BASICA, GWBASIC) on the original IBM-PC and compatibles. However the silent operation of this fanless and HD-less computer was very comfortable. So was the ability to keep its programms in memory even if the machine was switched off. Also fine: Avaiability of both a mass-storage device (a reliable micro-cassette) and a (tiny but noisy) printer (only 20 characters wide, like the LCD-screen) - all together squeezed into a A4-paper-sized flat box of acceptable weight.
