Subject: [Electron] DFS

Hi,

apart from the Cumana DFS (which I can't seem to get hold of), are there any
other Electron implementations of the regular DFS filing system? What memory
map locations do BBC ones use? Just on the off chance anyone knows, are
there any BBC DFSs which don't clash in memory map terms with the Electron
ULA?

An option I am considering is writing my own 'pseudo' DFS, i.e. something
close enough to an actual ROM to be called by the OS, but which actually
triggers C code in my emulator for its functions. It'll be much easier to
debug that way. As I'm sure such things have been attempted and completed
before, can anyone give me any pointers or even point me at just such a fake
DFS?

Thanks,

-Thomas
