808 State Discussion

I'll go with the Feb 1990 date, it can't be Oct 1990, I have it on Sasha and Sven Vath mixes from May 90 to name a couple.

Looking for a month - I know it was earlier 1990, I can't find out on the internet, wondering if anyone here knew?
Have an old Spinmasters tape and it's the week Cubik was released - so trying to put a date on it...
Cheers if anyone can help
