Are you able to quote chapter and verse wrt "emulators owned by DEC"?

I was aware of goings on related to a couple of PDP11 emulators inside DEC, and neither of them was SIMH. Doesn't mean that SIMH activity wasn't going on in parallel, mind you. But I have no recollection of word of DEC offering SIMH ever reaching UK customers.
