I mean the number WIZARD.BAS calculates and tells us to write down because
we'll need it when we make a drive descriptor for OS-9. If the drives are 40
tracks instead of 35 (on a 256 drive setup), the HDB partition will be about
23,000 sectors larger than what WIZARD.BAS expects, right?

Money's tight... I am still unemployed. I'd rather assemble them myself and
save the money for a hardware upgrade, like a SuperIDE or Pro-tector.

I have a Glenside compatible... Paul Barton's Pocket IDE, which will eventually
become part of the CoCo3 Portable. Right now it's hooked up to my repack, since
that's the one with 512K.
