The Background should be white - I guess you just have to change
brightness and the Bar will also change translucent - almost
invisible. The bar is common to all ZX81 and Timex and an is
artefact of the generation routine.

Maybe the output voltage of the video circuit don't reach
a sufficient height. As far as I remember there is an
adjustable resistor for that, so you don't have to change
all TV sets.

Hey, what you want - the ZX81 was just 300 Mark at introduction !
Every other computer just trippled this price (or 10 times, like
an Apple //e). And speaking of the Apple: no motor control !

And for the keyboard: there have been plenty of kits, and it
should be possible just to assemble some switches as a keyboard.
Try a web search.

Gruss
Hans
