I'd seen mice in the storage room where the TRS-80 had been kept loosely boxed up, and I had noticed some "poops" in the box... which of course ticked me off and I'd washed off the outside of the unit before setting it up, but I hadn't caught on to the fact they'd actually gotten into it. But, no, I didn't catch the actual perpetrators. :^b

In the end it's probably a good lesson about packing things up *carefully* if you want to keep them safe. You can never know for sure whether vermin might be a problem or not. (Years ago I stayed in a college dorm which had been completely refurbished top-to-bottom only about a year before I was there, and it had a mouse problem... actually cornered and caught one of the little buggers with my bare hands after spotting him emerging from a tiny little hole in the closet. And of course today I live in what appears to be a fairly idyllic suburban neighborhood, and *everybody* has rats in their garages. I've even seen them running along the cable TV lines between the backyards. Haven't tangled with a rat yet myself, and I'm not looking forward to it.) :^b
