Hi Don,

The light tells us there is +10T but not how far it is being distributed.

E1 DSP Data Lst a fairly common error - just means some data was not  
processed, but may be significant in this case. Usually seen when doing a  
screen save to a floppy or something that keeps the serial line busy.
STONE is an information display, means the sidetone key combination is the  
last key press.

No Side Tone ? Could be a L/R error in wiring. This is an easy fix, but I  
have to look up the wires involved.

More later
