ASCII Keyboard (Electron)

ASCII Keyboard (Electron) Photo

Based on the issue 4 schematic, the original System keyboard had a latching CAPS LOCK key switch, these are hard/impossible to find and so an alternative electronic implementation has been made using a second 555 timer (IC8).

The keyboard requires a donor Electron computer case and keyboard as well as a set of BBC computer keycaps (the original Electron keycaps could be used but I don't think they look as smart).

The Electron keyboard mounting plate needs to be modified to allow for the repositioning of some of the keys:

The Electron case requires modification to allow for the extra keys and holes drilled for the LEDs, the board then directly replaces the original Electron keyboard PCB.
