Epson HX-2023 #piday #raspberrypi


The Epson HX-20 was the first “notebook computer” as Byte Magazine put it in 1982 “larger than a pocket computer and smaller than a briefcase computer,”

Don over on lovingly reimagines the Epson for 2023 as the Epson HX-2023/cyberdeck. Powered with a Pi and a bunch of Adafruit goodies, including a KB2040 – RP2040 Kee Boar Driver.

Thanks for sharing! This is version two what will version 3 bring?!

There’s no 3D printing here. Everything was done by hand using various Dremel tools, ‘Xacto’ knife, and lots of sand paper.

The original keyboard is wired to the KB2040, programmed with KMK. This is then wired to small USB 2.0 2-port hub. One of the original USB 2.0 ports was rewired to provide the signal path to the hub and back without the loss of an additional USB port.

The USB 3.0 port stack was modified to a single port. The 2nd USB 3.0 is rerouted to a custom cable to the SSD.

The GPIO on the Pi has been flipped to connect to 40pin to FPC on the underside to fit. The matching FPC to 40pin was also de-soldered and flipped also to fit.

Even though the computer is from the 1980’s it’s quite compact.

LCD bezel was custom made from expanded PVC plastic board.

The rear and side plates are made from acrylic sheet.
