By "running" I'm referring to the IBM OS that will load and use the load module, not to the system used to transport it. AFAIK IEBCOPY load does not depend on recognizing the source device type.
Given that the OS/360 turnkey system supports 3330, why the concern for 2314? -- Shmuel (Seymour J.)

It does this all itself - not using any IBM tools. So there is no question of "supported system". The only question is "which virtual supported system" do you wish to emulate? It can emulate a 2314, a 3330, a 3390. It's up to me to specify "user requirements". > then use 3390 with a block size compatible with the smallest > track size you have to load to. If it's 3390 to 3390, I'd use 32K. It will almost certainly be 3390 to 3390, but I see no reason not to use a blocksize of 6144 - IBM products are normally/often/ traditionally distributed with such a "universal block size". And then yes - it could be restored even to a 2314. Although I am still unsure about something. Is it correct that an unloaded 3390-residing load module on a modified MVS 3..8 system with a block size of 6144 can be loaded to say a 3330 on an unmodified MVS 3.8 system (that knows nothing about 3390) because the required device characteristics are self-contained in the IEBCOPY unload format and IEBCOPY can thus deal with unknown devices?
