Hi,
This is a reply to vp's message of November 5 which is now inthe archive.
I also have some damaged HP-85 tapes, my thoughts were to punch some new holes inside of the damaged area (to become the new EOT / BOT markers). This probably is no good in helping to recover data, but would allow the tapes to be re-used.
Experiments so far have not been successful, I think a flat pin and die with sharp edges are needed:
| |
| | <- punch
+--+
------------- <- tape
----+ +-----
| | <- die
| |
| |
Regards,
John
