After all, I had to create a set of boards to clone my beloved first Sinclair ZX81 computer. Using the Baffa-2's CPU and Dual Clock board, it is possible to add 3 more boards to provide 32KB Ram/Rom, Keyboard and Cassette and Video I/O to build a ZX81 Clone.

In this photo, the Baffa-81 is using the new Baffa-2 backplane lite which has only 6 slots (original has 12 slots). This option was created because it is cheaper and can be used on smaller sets of boards.
