If I'm not mistaken, TK70 drive can read but not

I have very limited experience with this family of drives so far, but what
little I have is not good. Pictures:
Maybe my tapes need baking or something to keep the oxide from shedding? I
haven't tried it yet. Unfortunately, my failure mode results in a
labor-intensive fiddly manual tape extraction job followed by manually
rewinding tapes into cartridges designed to make it very difficult to do
anything manually, so I haven't found the motivation to resume
experimenting yet. If and when I resume experimenting, I might look into
making some sort of gizmo to let me unlock the two cartridge spool locks
and then manually rewind the tape, without needing to disassemble the
cartridge with springs popping out all over the place. Maybe something 3D
printed the depresses the latches, with a crank that engages the spool?
Yikes...I hope mine turns out a bit more reliable than that. As it turns
out, I bought a spare TK70 a while back at a hamfest and rediscovered it
the other day, so if all else fails, I guess I have that to turn to.
Is your 730 booting VMS yet?
