I dumped almost 50 TU58 tapes. They were given to me by an ex DEC FS engineer. Most of them are various 11/750 diagnostics. The tapes or not the official DEC TU58 tapes but home brewed tapes used in FS so there might not be an exact match to existing lists of official tapes. But they might be useful anyhow. I have seen diags for CI 750, DW750, RH750, DT07, Various Ethernet, UDA50, TK50, DZ32, DMF32, DH11 and some more standard 11/750 MIC, DPM tests and instruction tests. Then there were some 11/730 tapes. Console and two diag tapes. I collected everything in a google-drive-folder https://drive.google.com/drive/folders/1CkcXVJS9aJDwD4ihdj27QYcgkm7gEdrQ?us… This folder also contains some older dumps I have done. Both DECtape and DECtape II. All dumps are aggregated into a document trying to give a hint on what the dump contains. Beware that some dumps failed to read correctly and are just partial. But it should hopefully be clear from the file size. https://docs.google.com/document/d/1vD8erJM-HitSd4kRXt6_Rzl403HDoprr08EY69u… /Mattis
