Hi Peter,

I am afraid we can't make that assumption until the logic that controls
IC31 has been tested. This device is basically a switch. You apply a
binary pattern to lines A, B, C and INH and this determines which one
of the outputs is connected to the input. The input is marked X the
outputs marked X0, X1, X2, etc. It is the outputs which we just tested
and which don't seem to move. Tell me, do the voice LEDs (D10) come on
in order in Unison mode? Everytime you press a key an alternate voice
LED should light up. I suspect not?

Can you lay your hands on a logic probe at all?

Cheers,
Andy
