Hello everyone,
continuing with sparc64 testing I made the mistake to insert a floppy into my Ultra 5.
Most likely the first time ever in the 10+ years I own it, …
I realize this is certainly of as low priority as it was for me the last decade, but maybe someone is interested nonetheless (or it just works in Debian ;-)
I took the effort to connect another known good PC floppy (just to rule out hw failure) with the same result:
