I'm not an expert at this at all so take what I say with a grain of salt. I just happened to have two (uninformed?) thoughts:
1. If Enzo wanted to write some bare metal code (which I think is a great idea) -- are there any examples anyone can point him to? Is there any IPL-able code on the CBT tape or other more-or-less public source that would serve as an example? 2. A cross-assembler or an assembler running on Hercules would seem to me to be useful and necessary to the effort. (Perhaps that is so obvious as to not be worth saying.) I am trying to picture how nowadays one gets from classic object code to something one could IPL. The last time I IPL'ed something that was not a disk-based operating system it was a standalone dump on either cards or tape. I seem to recall there was some sort of a "link editor" that would produce an IPL-able image but I do not recall what it was. Actually, I have not IPL'ed a box at all since I owned a P/390. What media will a z114 IPL from, other than DASD?

As far as bare metal programming Hercules emulator on your PC might be easier to write and debug with before putting on actual hardware.
