[Coco] Preliminary Support for SDC in HDBDOS

[Kip Koon]

Hi Brett,
Maybe there could be an 8K and 16K versions.  I for one have no problems whatsoever have a 16K HDBDOS rom image running on my system.  The extra space would enable it to have all the drivers and features in one giant image, would it not?

Right now, it assumes a max sized partition, 256 disk.  I have to add one more method to flesh out the HDB Driver.  I would like some people to test the ROM out before plopping it by default onto the SDC image.
If  you try it let me know how it turns out.

I don't think I can fit all the fancy stuff, like Darren's SDCDOS into 8K.  And I'm pretty sure Boisy and Mark expressed concerns about HDB spreading out into a 16k image. So the fancy stuff my have to stay on a utility disk.
