Ben Versteeg is currently working on an external version based upon my original PS/2 keyboard adapter design. Being external means that it will be succesfully used both with the ZX Spectrum+, and with every other Speccy model. Besides, if you don't use more than a Spectrum at a time, you can have one of this, and plug it in the Speccy you want to use. Internal keyboard is not disabled during operation.

Ben's design allows for other peripherals to be used, as it adds a pass-through connector. Ben is currently accepting orders.

Internal keyboard

I got one of Ben's Keyboard interfaces. Great stuff! But I noticed that the internal keyboard IS DISABLED! Ben explained me why:
The PC Keyboard interface uses a driver (74HCT541) that is triggerd at the same moment the internal keyboard is read out.
So the PC Keyboard interface overrules the databus when the keyboard is read by it's own data, causing the internal keyboard not to work.
