524.0. "1.2 Megabyte with SF314" by HAMSUP::PETERSEN () Sun Jul 02 1989 09:25

    1.2 Megabyte on a Floppydrive sf314 !!!!
    
    only by changing the Clock from the wd1772 of 8Mhz to 10.24Mhz
    it is possible, to format (with hyperformat 3.2) a normal
    Floppydisk with 14 sectors.
    
    I have build in this option 3 days ago, and i have made a
    backup of a 3 Megabyte harddisk-partition with 3 Disks !!!
    
    If someone is interested, i will send a copy from the software
    (only the hyperformat) and a copy from STMAGAZIN 7/8 89.

    		( 1.2 MEGABYTES MORE SYMPLY)
    You can also get 1.2 Megabytes or more without extra hardware !!
    You just need to turn down the speed of the floppy-drive
    with 280 rpm you get 1.2 Mega
    with 270 rpm you get 1.5 Mega
    but you must use good quality diskettes
    
    you can also make a switch on the drive (Resistore) on the speed Poti
    so you can switch from 280 rpm / 300 Rpm
