Epson HX-20 Programs

NEW: Download programs from the distant past that will make the world's first laptop (the Epson HX-20) come ALIVE again. Digitally restored from micro-tape. These programs are not compatible with other RETRO-PCs; not even the Commodore 64. The HX-20 allowed the programmer to use commands that were unique to its 120x32 pixel screen, piezo-electric speaker, 8-bit ASCII character set and RAM pointers; all which I took advantage of.
