| - | This is an internal design that needs to be fitted over an existing chip as well as a few lines to be soldered to various points on the CPC motherboard. It's a DIY kit, essentially. No direct orders, so you have to register on the CPC Wiki forum and contact the designer on there. //Note: As of 2019, the developer is no longer making these available.// | + | This is an internal design that needs to be fitted over an existing chip as well as a few lines to be soldered to various points on the CPC motherboard.

| In short, it's very delicate, but only 8x 100Ohm resistors are needed (obviously the traces need to be cut for each one also). The //nicer// solution would be to connect each resistor to a multi-way switch so that the original, unaltered data path can be restored, if for example you decide to disconnect the external keyboard.... though I would guess it should still work when the external interface is removed. | In short, it's very delicate, but only 8x 100Ohm resistors are needed (obviously the traces need to be cut for each one also).

| + | Note: this is another design that will not work on the +2A, +2B or +3 due to the way Amstrad redesigned the main board. This is again for 16K, 48K, 48K+, 128K and +2 models only. **I think I'm going to have to downgrade from the +3 to a +2 in order to get PS2 keyboard support....** | ||
