thanks a lot for the explanation! Indeed I'm going to try to save it
from the TIM later. I hope to have good results fiinally!
I think either the C2N I'm using or the tapes have some issues.
Writing anything on a fresh part of a tape works reliably. Ovewriting
something results in nothing read back.
I've found a similar belt to restore a second C2N, so I'll see if this
one works better.

Does anyone have a good suggestion to restore the gold-plated edge
connectors? The ones on this pet are badly worn out, the gold plating
has gone away on large parts. The connection is reliable enough with
the gold-plated connectors (like the one I built the PC64 cable with),
but the original C2N connector is already too unreliable to start with
I've had good results on the tape#2 connector on my 3032 which isn't
gold-plated but just tinned. The tape#1 is unreliable in this
semi-gold-plating with holes state.
