Hi Marc,
Thanks for the information and photos.
I'm pretty certain that BASF didn't make 6105. So if it's not an NEC
drive, it could be a YE Data drive.
But you're right--if you want a real mess, check out some old tape
autoloaders from around then. All those bits of rubber are now blobs of
goo--and tough as the devil to get cleaned up, much less replaced. Some
are worse than others--some drives from the late 90s are starting to do
this now.
