![]() ![]() The drive is powered on with both buttons depressed and it reads the software and updates the firmware perfectly. The Gotek USB stick is formatted in FAT32 on Windows and has a copy of the latest QD firmware saved on to it as a. Setup Instructions I reprogrammed the Gotek drive with the commercial HxC firmware (£10) as my drive was programmed with Flash Floppy when I bought it, which does not work with the QD software. The original 10-pin grey connector on the QD is close to being a JST connector, but it needs a little bit of work with a craft knife to smooth the sides so it fits. The PCB is 150 x 120 mm and contain a JST 10 pin connector for the cable to the Roland main board, a 34-pin IDC connector to attach the drive to, along with 4-pin power. I took 1 mm off each side of the drive using a craft knife and then designed a PCB that attaches to the base of the drive and to the QD metal mounting bracket, so the drive is at exactly the right place. The Gotek drive casing is 2 mm wider than the QD drive and 2 mm smaller in height. In mid August a version of the HxC code was announced that supports Quick Disk and I have tested this out on a Roland S-220. Kief Fraser is the developer behind Flash Floppy and he is also working on a version as well and the wiki is here. The QD uses standard MFM encoding (its a DD disk!) and has a clock rate of 101 kHz much lower than the DS/DD floppy drive clock of 250 kHz.Ī QD Solution Jean-françois Del Nero is the developer behind a Gotek HxC firmware update that supports Quick Disks, details are here. ![]() The read and write hand shaking is very basic and described in the Roland services notes. /RESET set low for reset period after POWER ON RESET./MEDIA SW – indicates disk is inserted or not./READY – reading or writing can take place./MOTOR ON – Low sets the disk motor running./WRITE DATA – data is written here when WRITE GATE is high. ![]()
