Do you feel like having ago at repairing the 5151 monitor? I have 
schematics, and it's a very simple circuit. In fact the most difficult 
part is getting inside the thing.

(Prise off the little caps at the front corners of the top grille. Put the
monitor face down. Free the cables fron the 'hook' on the bacb section of
the case. Undo the 2 screws under those caps, the 2 screws on the bottom
that go in from the back. Peel off the sticky paper on the bottom, undo 
the 4 screws on the back half of the case _NOT_ the 2 on the front part. 
These 6 screws hold a bracket inside that holds the mains transfromer, if 
you remove all 6 screws it fals onto the CRT!. Lift off the case).

This is a thinly disguised Epson printer, of course. Again I have 
schematics if you want to attempt a repair.

In my experience logic faults are rare in these keyboards. If it's 
totally dead, I'd suspect the cable. At least one of my IBM keyboards has 
been fitted with a new DIN plug.

If odd keys don't work, you might find dismantling the thing and cleaning 
the PCB helps. I can talk you through this.
