This is my first post, I recently got a couple of SInclair 1000's and
ZX81's.

I must be doing something wrong...I have USA units. With a standard
RF converter and apater to convert the signal to a cable-in jack - all
known working equipment - I get a prompt, but it's very dark. In fact
I have to bring the contrast and brightness up all of the way just to
barely see the prompt.

This subject may have come up before...what's the solution? I even
tried a signal booster. Please .cc replies to billdeg at aol dot com.

Thanks.
