This is not true.   The drive is pretty much the standard 5 1/4" drive
(of that day), but the controller is completely different.
Heath/Zenith and a number of third party suppliers sold soft-sector
controllers (called H37 format), but I'm not aware that any of these
would also do hard sector (though I guess that could be possible).  Many
people had both hard sector and soft sector drives on H-89s.

You either need to move stuff between the machines the with the serial
lines or install a soft sector controller in the 89 (not too easy to
find now).  

HUG sell (for about $15) a package that allows a PC to emulate an 89.
This includes a pretty nice utility for moving stuff between them with
the serial lines.
