DreamPark Development in Utah ((801) 943-4370) sells both 1.44 meg boards
and boards with drives if you don't already have a high density drive. 
Installation by a qualified technician is recommended unless you are a
competant hardware hacker since installation involves cutting out the
WD1772 controller chip, soldering a socet in it's place, and running 
several drive select lines from the sound chip to the new disk controller
board. Install an autofolder driver and away you go. 

Mine has worked flawlessly since I installed it several months ago. Very
nice since because of the 2x data transfer rate of the high density drive,
not only do your floppies hold twices as much data, but the read and write
twice as fast.

I am not in any way connected with DreamPark Development.
