mainframe EBCDIC FAT (Announce)
So is it possible to port msdos to an IBM mainframe?
Obviously it has a different instruction set. S/370 etc. So since MS-DOS was written in 8086 assembler it needs to be rewritten. Language could potentially be anything. CP/M was written in PL/M.
I chose C.
But the FAT file system is the same. Except the mainframe uses EBCDIC normally. Can the FAT filesystem even work on EBCDIC?
With the benefit of hindsight, everything becomes obvious, allegedly.
Anyway, it's not quite hindsight, so I wouldn't say it's a done deal. It's still a work in progress.
But you can see for yourself by searching for z/pdos-generic at http://pdos.org and downloading zpg.zip
You will need a different emulator for the mainframe. I use Hercules/380 but standard Hercules works with workaround.
