Following up:  It turns out that this is a hardware incompatibility 
between the Omnikey and A3000/A4000 Amigas.  When first started, the 
keyboard is dead but if you leave it be for a minute or two it spits out a 
few lines of garbage and resurrects itself!

I found one cryptic reference to a small assembly-language utility called 
TICK_NORTHGATE that remedies the issue, but cannot find it in any of the 
usual places.

In the meantime, I'll just try to have patience.  The keyboard must have 
been (mis)behaving in this manner since day one on the A4000 and I simply 
never noticed it.
