[comp.sys.atari.8bit] US Doubler & MS-DOS Disks?

rrwood@contact.uucp (roy wood) (10/09/90)

I guess my last attempt to post this didn't quite work, so here we go again...
 
I just picked up a 1050 drive with a US Doubler installed.  Does anyone know
if there is software available to allow it to read/write MS-DOS disks?  The
SpartaDos manual shows that the SIO command "Set Configuration" ($4F) involves
sending a 12 byte data set that includes the sector size.  Theoretically,
one should be able to set the sector size to 512 bytes (instead of 256) and
read/write MS-DOS disks, right?  Well, now how do I specify the 12 bytes
to send?  Where in SpartaDos is this set?  Will I have to hack the code?
 
Also-- I know about the PC utility for reading/writing MYDOS format disks,
though I'd like to be able to read/write on the 1050 too.  And I also know
that Happy-enhanced disks can read/write MS-DOS disks (I have a Happy on
order from B&C).
 
Any hints or suggestions will be appreciated.  Maybe I'll go look at the
tech. ref. manual and see if I can fake the entire SIO send sequence and
generate the 12 byte data set myself....
