I went with some friends to see Die Another Day about a week after it's initial UK release and the 2 screens showing this flick were still full to bursting. Undetered, we went to another (THX) cinema about 20 miles away at 11.00pm and while DAD may not be the best Bond film ever created...
If you take a look at the BBFC's web site (www.bbfc.co.uk) it states that Terminator was classified on 30th November 2000 with no cuts. Doesn't mean it's the same as the R1 version, though.
There's also a piece entitled "The Terminator - deleted scenes", which was also passed without cuts...
