An interesting site (BMPG) - my nearest approach to Bloodhound happened when I got on the wrong coach, one morning at North Luffenham in 1962 and ended up at the local missile site - promptly rejected as not holding clearance(s).
If the BMPG team have produced a simulator they may have used Coral 66 files to drive a virtual Coral 66 interpreter on e.g a Rasberrry Pi, the original systems have long been withdrawn, so no risk of a hacker gaining much from the old code. Try them - the worst they can do is ignore/refuse any such request.
One of the contributors above has linked to two Coral 66 programs that could serve your needs for test material. ( Oldben, I think). Anyway - have fun…
