Well, the Northstar now sports a nice clean pair of Shugart SA400s in its
drive bays, both of which work fine. I cleaned up the aluminum chassis
with some rubbing alcohol (though I have one handwritten sticker on the
front left to remove). It spiffed up real nice!

On a disk that Doug Coward sent me, which doesn't boot but can be read
once I boot of one of the disks sent to me by Don Maslin, I have a
couple programs called RAMTEST3 and RAMTEST5. They're purpose is
obvious BUT I don't have any docs for them. Does anyone have information
on the various values it can show for each 1k block of memory it examines?

Thanks...
