Due to some internal limitations, a dual drive takes up 2 device numbers, so the first 8050 would be at device 8 and also make number 9 unavailable. The second 8050 (or 8250) would be device 10 and make 11 unavailable. That is because internally VICE only knows about 4 floppy images. The gtk3 settings windows in the current svn version doesn't seem to represent this 100% correctly yet, I see now that I'm trying that. I'm pretty sure this is shown correctly (but possibly somewhat confusingly) in the menu settings in older releases. > I want to run Super OS/9 with this configuration also - i have the relevant > os9.d8d9.mod module to enable multi unit capability. > > I can have one or the other but not both .... any ideas or is this a > limitation of Vice ? Maybe the OS/9 code cannot handle that it needs to access drive 8 and 10, instead of the probably more common 8 and 9? > Also, I have been working in OS/9 - on my real unit, I can create a ram disk > by issuing the command format /dram without any issues. in VICE when you > issue a Format /dram command from the os9: prompt it goes through the > formatting motions until it asks for the disk name ... after that it just > hangs. Any ideas ? There might be a bug in the 6809 code, who knows. It is only lightly tested, really. I briefly tried OS/9, I think, and saw it didn't crash, but no more. In particular the 6809 is not cycle-exact; maybe that would be a problem? > Cheers > Andy -Olaf. -- ___ Olaf 'Rhialto' Seibert -- Wayland: Those who don't understand X \X/ rhialto/at/falu.nl -- are condemned to reinvent it.
