I have a RS TRS-80 5 Meg external hard drive on the auction at Ebay. It's in good physical condition but I don't know the working condition. Someone pulled one of the interface cables out. There is a picture and a little more info in the listing. Only going for $20 so far. Auction ends Thursday 1:15 PM. http://www2.ebay.com/aw/itemfast.cgi?item=inz25894 Thanks, Greg
