This is a revision version of the Mechtrum ZX Spectrum with a mechanical keyboard.
I have designed a new keyboard PCB to make use of the Wraith Keycaps found on Aliexpress
It supports original 48K spectrum PCB and modern Harlequin boards.
The new Keyboard PCB
These are the thin Keyboard PCB connectors that replace the membranes.
