I think that my door has worn out or broken where the slot you mention is.
I can see what possibly looked like a place where the spring would have
engaged... but it isn't possible any longer.  My VHS hub lock mechanism
spring works nicely though.

However, now I can't get by a problem where I can't write to tapes (I can
read).  It thinks every tape is write protected.

Going to check out that area of the drive now...

Anyone ever see that problem in a VS80 before ?  Wondering if that is
how the drive got 'retired'.... and ended up getting to me (since I'm
two people down the chain from where the equipment originated, I
don't know the history... but the Optiplex GX260 and two Optiplex GX400
systems both worked fine, so I had high hopes for the tape drive (although
I suppose in my tear down/reassembly I could have messed up something
(maybe the small ribbon isn't seated right ?)
