The other wrinkle is that HDBDOS only uses half of each 512 byte sector. 
Considering that a "marketing" MB is roughly 1,000,000 bytes, 198 disks 
is about right for the max on a 64MB card.

I'm used to doing all this with the DW4 version of hdbdos and using 256 disk images, but I would think it all works the same.

That's what the user manual says that address 0x0150 represents.> Also, the os9 partition size limit is about 128meg using a cluster size of 1. Anything larger (up to 4gig) uses larger cluster sizes.
