Just a quick update - now have just one of the five H/Ds working, (the Seagate SCSI) but flaky as hell!

The saga to arrive there is too long to write, but ultimately was down to (literally) a flick of the wrist !

I'm still no closer to what the cause was and still not able to use the mouse. Ah well, back to the drawing (mother) board.
