Those are strong words -- false advertising.

Did you get 110MB of disk storage?  Then you did indeed get what you were
told you would.  Absent any claim of the technology used to get that
storage before the sale, you don't have a point or a complaint.

If you were/are concerned with the interface details, you should >ask< 
before placing your order.

The $95 may have covered a better controller and/or a certified RLL disk
drive.  I don't know, since you didn't quote model numbers off the parts.
If you had, someone (myself included) might have been able to tell you.

Ditto.  We use the WD1006 series here, and the Adaptec ACB2372.  Both work
just fine.  The WD1006 is faster under Xenix, there is less difference under
MSDOS or ISC Unix.
