Hi, yeah - had also contact with Mattis in the past about his tapes. He also currently no way in backing up his tapes. Even if the tapes are fit into QIC-11 tape drives, just remember that no regular QIC tape will be able to read them. They are MFM encoded. Here you'll find the manual of the drive used in the S8000 http://www.bitsavers.org/pdf/dei/CMTD-3400S2_4tk6400bpi_1979.pdf Attached you'll find a text file I gathered from somewhere stating that it is the service manual of the drive. You'll see that its "features" are a bit of from QIC standard - it was made in a time where QIC wasn't that popular. But maybe you're backing up strategy with a logic analyzer does not care about all that? I wonder how the recorded data could be then possibly restored on other tapes to create a copy for example?

Speaking of rare QIC tapes, I've undertaken quite an effort to read previously unreadable or unknown QIC tapes:
Soon, I'll do a video demonstration of the programs I wrote which read the data from the logic analyzer captures.
I'm pretty excited about the success of this project.
Also, maybe on topic here, I was also dialoguing with MattisLind from Sweden about preserving some rare Zilog 8000 Zeus OS tapes, where he doesn't have any hardware that will read them.
He asked if I was going to come to any of the Infoage/MARCH events such as Festivus, and that's where we left the conversation off. It would be a shame if he came with the tapes all the way from Sweden, and I missed him.

Welcome!
and I'm looking for information about the Zilog System 8000. I know that
you owned at least one in the past. I don't know if you still have it, but I hope so :)
We have it, but we haven't done much with it. Perhaps at our next repair event. We have workshops here every few months.
Ok, I'll look forward to that - hoping that it will happen some day ;)
Just remember the tapes are quite rare and need be handled with care. Your tape drive has also a capstan which went to goo over the past 30 years, so please do not just put them into the drive without fixing that first.
Otherwise the tapes and their contents will be gone forever....
