Here's what I do:
1. Use VMSTPCE to image the tape on a VMS box.
2. Transfer the image into a VMS system running under simh.
3. Use VMSTPCE to write the image to a simh tap file via an emulated TK50.
There may be some more straightforward way to convert a vmstpce file
to a simh tap file. If so, I'm interested in hearing about it.
You can find VMSTPCE here:
I'd also clean the TK50 and TZ30 drives and test them with scratch media.
Clean as needed (each use?) and be grateful for every tape the drive
returns to you unscathed.
