Good news: my "new" logic analyzer was d livered today, it was not damaged by postal services (despite the postman letting the package fall on the ground in front of me) and it powers up fine.
Bad news: either the floppy drive or the (orginal) system disk is not working. Spent a couple hours trying to find a working floppy drive and old PC in my parts stash to write a new system floppy. I think my computer from 2003 has a bad floppy controller, couldn't get that to work...
