Quick Disk

FlashFloppy features an alternative firmware emulating the 2.8-inch "Quick Disk" drive, used in a wide range of 80s synthesizers by companies such as Akai, Korg and Roland.

Tested Systems

• Akai: X7000¹
• Roland: MKS-100², MT-100², PR-100², S-10², S-20²
• Sharp: MZ-800²

1. Pin order is reversed from order below (ie pin 1 is GND)
2. Requires jumper at JC in addition to MO

Programming the Quick Disk Firmware

Follow steps for Firmware Update but use the update file contained in the alt/quickdisk subfolder of the FlashFloppy distribution.

On successful update, when USB stick is ejected you should see q-d on the Gotek display (this replaces F-F on the standard 3-digit LED display). On an LCD or OLED display [QD] is shown.

Jumper Configuration

The Quick Disk firmware requires a jumper at location MO. The usual drive-select positions S0 and S1 are unused and should not be jumpered.

Roland hosts (eg. MKS-100, MT-100, S-10) additionally require a jumper at JC.

Connecting to the Quick Disk Host

Wiring is as follows. Note the conventional QD pin numbering and wire colours. However this may vary on some hosts (for example, Akai and Korg may number the pins in the opposite order, and use monochrome cabling).

QD Pin	Wire Colour	QD Interface	Gotek Pin
1	Brown	/Write Protect	28
2	Red	/Write Data	22
3	Orange	Write Gate	24
4	Yellow	/Motor On	16
5	Green	Read Data	30
6	Blue	/Ready	34
7	Violet	/Media Sw	2
8	Grey	/Reset	20
9	White	+5v (Power)	+5v
10	Black	Ground (GND)	GND

All other pins can be left unconnected.

Using the Quick Disk Firmware

Usage is straightforward and very similar to the regular firmware.

• QD firmware supports only QD images (.QD file extension)
• A blank QD image is provided in alt/quickdisk
• FF.CFG is processed as usual, but do not modify drive-related options
