-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.//

+Don't have one (yet), but this enables you to use a PS2 keyboard on a VIC20, C64 or C128.
 //"Depending on configuration, C=Key offers VIC-20, C64, C64C, SX64, C128, C128D, and C128DCR owners the ability to either use their CBM keyboard with a PS/2 supported PC, or utilize a PS/2 keyboard on their Commodore machine.  In either usage, multiple keyboard mappings are supported, to handle keyboard differences and application preferences.  No drivers or programming are required for operation.

 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.
-A detailed diagram of which pins are needed to be altered is to follow below.

+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....**
