VERY basic linux system 246

Grant Edwards

In a floppy based system, disk names work better than drive letters. Ideally, you have both, like the way the Amiga did things. You could use FD0: to identify whatever disk (if any) was in the first floppy disk drive. Or you could use DiskName: to identify a disk by name. If that disk were in a drive, it would use that floppy. Otherwise, the computer prompted the user to insert that disk into any drive.

The OP's desired OS features seem rather heavily inspired by the Amiga OS, which I would have mentioned except he's obviously already aware of it.

Incidentally, the Amiga OS also featured a single user flat memory space. This did have some performance benefit- -"kernel" calls were direct JSRs (IIRC) with no context switching overhead. Of course, this approach made security entirely non-existent. Any process could take down the whole system with errant memory access. Still, at least it had pre-emtive mulbreastasking. Thus, the system wouldn't just freeze up due to a bug in one process. So long as all the processes behaved well on the memory access front, you were okay...

buttuming the OP is familiar with the Amiga OS, he should already be aware of some of the pitfalls involved.
