Who can identify the platform, these CDC diagnostic floppies were made/formatted for?

Hello everybody, I'm holding in my hands four 5,25 inch floppies from CDC, more specificly from their division Magnetic Peripherals. These came with some FSD-drives a couple of years back. Google turned up with not a single hit, when looking for more information about these floppies. They are marked with "1244-00,? souble side, single/double density, soft sector, 35/40 track" regarding their type. That's written on the etiquette: 1. SDI diag. disk PN: 92989602 2. SMD-0/E diag. disk PN: 93290704 3. SMDSTD, SMD-0 PN: 93290703 4. ISI diag. disk, PN: 93845702 ? I'd like to save the contents and maybe use it, as well, but I have no clue for which platform/system they are. Can anybody help me on that? Thanks alot in advance for your help!
