Old Suunto dive computer manual?

Hello. This is my first post in here.. i hope i don't end up on a few dozen
spammers lists.

I have recently pulled out my dive gear after a 14 year hiatus and much to
my surprise, my Suunto dive computer still works good as new. I took it out
to the pool a couple times and the battery seems fully charged. Hard to
believe I know. I'm not going to put too much reliance on it. Anyways. I
can't find the manual for the silly thing anymore.. too many moves and too
many boxes of junk laying around.

I'm wondering if anyone on here would happen to have a manual for such a
dinosaur? This must have been one of the first Suunto dive computers made. I
bought it in England back in 1990. It is round on top, and square on the
bottom, and fits into my console pack. To turn it on you place a wet finger
on a small pad at one end, or submerge with it and it will turn on. There
was a way to make it display each previous dive info, but I can't remember
the combination. It was something like 6 slow taps on the button, followed
by 3 slow ones.. or something stupid.. Anyone know the answer to that?

I checked the Suunto site, but they only have named computers now and I
don't see anything that looks like this old one. I don't think it ever had a
"name".

I can send a pic if that would help anyone.

Failing this, I will email Suunto.. but they likely will charge me to get a
manual now and a reply might take weeks.

Thanks

Doug.
