Floppy Days 95 - The Epson HX-20 Part 2 With Earl Evans
The Epson HX-20, Part 2, With Earl Evans
Hello everyone, and welcome to episode 95 of the Floppy Days Podcast for November, 2019, where once again this month (in Part 2) we will continue talking about one of the world’s first portable computers: The Epson HX-20.
I’m extremely happy to again have my good friend, and vintage computer podcast legend, Mr. Earl Evans, as my co-host for this episode.
It turned out we had so much material to cover that I ended up breaking this topic into 2 parts. Last month was part 1, where Earl and I covered HX-20 history, tech specs, and peripherals. This month will be part 2, in which Earl and I will continue coverage by discussing how to use the machine, emulators, software, ads and appearances, modern upgrades, Web sites and more. In addition, I will include an interview with a gentleman who has done recent work around the HX-20 in the area of emulation, Mr. Pontus Rodling.
First, however, I will spend a few minutes talking about my recent acquisitions in the vintage computing space and what I’ve been up to, then I’ll cover upcoming shows.

http://starringthecomputer.com/computer.html?c=171 Epson announced the HX-20 to the world in this famous double page ad spread from 1982. Its compact size is obviously the big selling point here - http://www.ganjatron.net/retrocomputing/epson-hx20/creativecomp0183-2a.jpg another four page ad from Epson UK. Epson apparently wanted to make it clear that only they had the foresight to devise such a compact computing platform. As depicted in the ad, the HX-20 is equally at home in the office, on the plane, in a power station and at home. - http://www.ganjatron.net/retrocomputing/epson-hx20/practicalcomputing128202a.jpgModern Upgrades
