Replica Atom Keyboards

 There are three variants of keyboard that can be used with the replica Atom project (from left to right):

• 'Electron' - that fits in the place of the Electron Keyboard in an Electron case

• 'BBC' - this fits in an Atom case

• 'MX' - intended for a non-cased build (it does not fit in an Electron or Atom case)

The 'Electron' variant reuses the original Electron key switches (plus four extra), likewise the 'BBC' variant uses the key switches from a BBC Computer (please note this board is designed to accept the white Futaba switches, later types may not fit ?).  The 'Electron' can be fitted with the original Electron keycaps though I prefer the look of BBC keycaps which look more like original Atom Keycaps. The 'MX' variant uses Cherry MX key switches and is fitted with a standard set of PC keycaps.

I've added a page which provides some Keyboard Construction Guidance which applies to the Electron and BBC keyboards.
