|Assembled keyboard interface, with mounted LeoStick|
Underneath the LeoStick there is also space for a couple of resistors. The LEDs and a Momentary switch are attached to some more headers via some wires, and these will be mounted into the eventual case at convenient locations.
I ended up ordering some Molex connectors suitable for mounting a standard ZX81 membrane keyboard. The ZX8-KDLX I procured earlier is designed to quite happily plug into a ZX81 as a replacement keyboard. Using the Molex connectors rather than say IDC connectors, as could have easily been done, leaves options open if I ever decide to fully embrace the retro and go all membraney.
So now it's on to some case designing, as well as going back and reworking of the Arduino Sketches.
