I have managed to purchase two new 3-1/2" floppy disk drives for my Atari 1040STf. I don't know if the disk drives are high density or not, but they were manufactured by Mitsubishi and Chinon in December 1988. What is the best way for get them to work with my ST? I have the old TOS installed. Does TOS 1.4 support high density diskettes? Much appreciated Lyndon Handy

You have to replace something in the ST disk controller mechanism for this to work, as well as getting the disk driver. I've seen some company marketing a kit that will let you do this. ---jb > >Much appreciated > >Lyndon Handy

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. ____ ____ /\/\/\ Bob Luneski /\/\/\ \/\/\/ Diamond Back II Support Hotlines: bluneski@pogo.WV.TEK.COM \/\/\/ \/\/ Genie: B.LUNESKI1 CompuServe: 76635,2310 \/\/ \/ \/
