from a little earlier, and on the understanding that his request takes

my interest in a Music 4000 keyboard, on the improbably slight chance
that there happen to be two unwanted ones in Dorset....

one, and though I am not interested in parting with it, when I serviced
it, I saw it was a very simple device. I could trace out the circuit, if
you wanted to build one. As I recall, it's a simple scanning keyboard
device with very little inside the case apart form the key mech. I think
one of those cheap home keyboards could be recycled into one.

I have a
keyboard at home that I will (eventually) getting around to adapting, so
I'd be interested in the circuit for the Music 4000 keyboard, such that
it may be usable with my Music 500.
