[Coco] The difference between /SD0 and /D0

[Bill Pierce]

I was under the assumption that the CocoSDC was a WD1773 emulation, therefore /d0 should work on it as an RBF/wd1773 descriptor. I may be wrong in this assumption, as I don't have the SDC myself, but I thought that was the whole reason it was built.

Well I would not call it "right". :) What you are seeing should never happen as 
there are two different sets of drivers for /SD0 and /D0. I have a different 
pak, microSD by Roger Taylor, which has no problems handling pseudo drives on 
the microSD, drives on DW4, hardware hard drives on a Ken-Ton interface, and 
hardware floppies all at the same time.
There is no way I can test any of the SDC software without hardware. I also 
can't distinguish between software failure or SDC hardware failure.

Based on the NitrOS-9 source code, your OS9Boot file should include, rbsuper, 
llcocosdc, and sd0 for the SDC; rbdw, dwio, and x#s for DW4; rb1773, and D#s for 

floppies. These different sets should be invisible to each other.
If the SDC wants to emulate both floppies and hard drives, it ought to use the 
SD# descriptors for both and distinguish the format in the descriptors.

What do you see with
ident OS9Boot

===============================
Yes ed is the terrible editor that came with OS-9. There are several third party 

editors available. What you pick will depend on whether you want to write 
letters and document or source code.
I use scred very often as I normally write source code.
