Mac OSX cocoaMSX - Is there any MSX1 with FDD I could use?

I am using cocoaMSX and I can find in the list of supported machines a lot of MSX2 with FDD support, but all the MSX1 I tried to setup boots directly to BASIC, ignoring the MSX-DOS disk I mounted. I guess that is because such machine has no FDD controller.

Anybody knows if there is a MSX1 machine that has the FDD controller.

There are only a few MSX1 machines with disk rom (and some of them are limited to 360 kb dsk files). The most easy solution is to run one of the generic MSX machines, they have all a disk rom allowing to use 720 kb dsk files.

You can of course also use a normal MSX1 and add an external FDD, like the Sony HBD-F1.

CocoaMSX does not allow to add an extension. Crying
To get an MSX1 with 2DD drive You need select a generic MSX (Europeran, French, Jananese,..).
You can download the BIOS you want via the preferences panel.

@gdx : CocoaMSX has the same MSX databases as blueMSX, it means that the system roms can be used as 'normal' roms, what is not possible in openMSX.

So, for a MSX1 without disk rom, you can insert a disk rom in cartridge slot 1 or 2. But of course the solution of the generic machines is more comfortable, especially because a few specific MSX1 machines have built-in firmware that make impossible the using of a disk drive.

[offtopic, but FYI only]

Yes, that's by design. In our view, a user isn't inserting ROMs but hardware cartridges (that may or may not include a ROM). So in openMSX you insert what you would insert on a real system: an extension hardware cartridge, not a ROM file.

(For running a software cartridge, you can of course still use a ROM file, and openMSX will then automatically put an extension configuration around it, but no one will notice that... It would be a bit weird to specify extensions for all possible software cartridges... although nothing would stop you from doing that of course Smile But these are so trivial (*if* you know the mapper type!), that they are auto-generated when you put these in the cart slot.)

Anyway, using that blueMSX method, I guess you can still add that Sony HBD-F1 to the MSX1, by inserting its ROM, right?
