This kit is needed if you want to use 1.44 floppies on your ST/STE/MEGA ST machines. The board is fully automatic and will switch between 720K and 1.44 mode without the use of drivers or special software or TOS patches etc. You can use internal or external drives in either 720k or 1.44 mode. V7 series has the media change fix so TOS behaves better when the floppy is changed and also includes DMA pull up resistor which will help solves some DMA related issues.

PCB is as illustrated with SMT assembled only. You will need a MPF920 drive, item #0037. Header pins, item #0158. Socket , item #0221. V6C floppy controller , item #0227.
