dk'tronics keyboards

dk'tronics produced 2 keyboards for the ZX Spectrum: One of them with a large space bar. Both had an additional number block. The black plastic case was large enough to hold the ZX Spectrum, the Interface 1 and maybe the PSU or some other add-on. [not shure, whether the smaller version could be used with the IF1.] 

The Specci was removed from the original keyboard and placed inside the dk'tronics keyboard. Two leads with plastic plugs were inserted into the original keyboard foil slots. The leads were long enough so that you could use this keyboard for testing a Specci PCB outside it's case.

On most models the main keys were grey and the return key and the number block keys were red. But it seems there were also version sold with the return key grey and maybe the number block grey too. (at least there were ZX81 keyboards this way.)

A small PCB was stored inside the case which was required to elongate the Microdrive bus of the Interface 1, if it was fitted inside the case.
