MSX-ONE Keyboard
About the MSX-ONE Keyboard PCB
MSX-ONE Keyboard is an open source PCB design by jdgabbard, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 200.3 × 95.6 mm, with 87 components from 82 distinct parts.
Other key parts include the 74LS145 and 74LS07. By type, the board carries 73 switches, 5 diodes, 3 capacitors, 3 resistors, 2 ICs and 1 connector.
It belongs with the keyboards and retro computing designs in this gallery.
From the project
MSX 1 Computer from discrete parts
The keyboard circuit is completely working, and stands at vesion 1.0
I will likely add a different board layout using standard 1/4w resistors for the LEDs.
