The pcb replaces the plastic or metal plane at the backside of the keyboard (no need together with the stable pcb) depending on the version of the corresponding models.

Hard for me to work without.
I did the calculation of the project and the board is bigger than the 48K-KDLX and has about 50% more tactile switches.
The complete set (construction kit) consists of
2 layer pcb, 256x99 mm (10.0 x 3.9 inches)
58 ALPS tactile switches SKQGFAE010
2 flat cables to connect keyboard to the molex receptacles
5x 74HC4066 analog switches
4x BAT54A duplex diodes
11x BAT54C duplex diodes
1 capacitor 10uF/16V
4 resistor network 5x 100k
The complete set will be offered for GBP 24.00 nominal price on sellmyretro later and all preorders will have a discount of 20% which results in effective price of GBP 19.20. I think this is a fair deal for all supporters of this project. Shipment will be GBP 2.90 for all international orders.
Schematic is attached here as well.
All people interested in preorders may leave an informational post here or give me just a PN. Thanks.
Expected to be available for delivery in mid of december.
