For Linux on IBM mainframes, see http://linuxvm.org/present/SHARE102/S9236uw.pdf as a starting point. Also I've put info on assembler formats etc. at http://wiki.lazarus.freepascal.org/Assembler_and_ABI_Resources (I needed comparative info when looking at MIPS a few months ago), I was hoping to add links to ABIs for each architecture but didn't get that far since something else intervened.
I've added a fragment of assembler code (from the Linux kernel) to the above page as an example. Digging around, it looks as though Linux assumes at least an S/390 G5, according to Wp this model was released in 1998, I don't know whether any are still in service.
Noting Paul's intention to target MUSIC/SP, I think that the points that distinguish this are (a) it's compatible with older IBM OSes and (b) in conjunction with a suitable emulator it has TCP/IP. I don't think that postings earlier in this thread make clear that it's (apparently) the only free OS that has this combination of features, and whilst I've still got misgivings over e.g. its use of EBCDIC I can "see where he's coming from".
