7854 display set up procedure without the calculator keyboard

Martin Whybrow
 

My 7854 has issue with the readout, the characters are lines (no Y deflection) and are in the wrong place (all at the central grid line); I want to go through the display setup process, but that requires the keyboard in order to enter the program to generate the calibration pattern; unfortunately I never got the keyboard when I bought the scope, is there any way around that little problem?

There is one on ebay.

They are pretty rare these days.
