I just noticed that Epson's website contains product information
(including manuals and sales brochures) for some of its legacy products
such as the HX-20 and their old line of desktops.  Check it out:

They even have a link to contact support on the vintage products (though I
doubt you would actually get any help on them...it would be neat to try
one day however and see what happens :)
