Not for the moment, but if you can provide some informations i will have a look. Can you make a picture of the internal connection and of the FDC used on the motherboard ?

Reviving this old thread.

I have an Akai S-612 with MD-280 Quick Disk drive. The drive is not working but I'm reasonably sure the interface/controller board is working (powers up another QD drive scavenged from a Yamaha FB-01 -- but this drive needs a belt replacement)

Give me a day or two and I can upload pictures of the 10 pin connector and the controller board.

If we can get this working then it would also help Roland S-10 and Famicom Disk System owners.

Disk format, sector and track info:

I'm about 90% sure the FDS used the same format as the samplers. As far as I am aware no one has dumped/imaged one of the sampler Quick Disks to PC using one of the pirate FDS dumpers.

Hi,
We have some internals project to provide a solution to dump and emulate this kind of disk.
So stay tuned ;)

(Waiting for the pictures)

Is there a chance to get the floppy emulator working in replacement of a QD 2,8 drive ?
Like in Akai S612 / 700 / X7000/ X3700 - Roland S10 / S220 / MKS100 - Korg SQD1 / SQD8 - Yamaha MDF1 ?
In some Thomson and Sinclair computers too...
(Most of these Mitsumi Quick Disk drives are dead now).

Unusually, the Quick Disk utilizes "a continuous linear tracking of the head and thus creates a single spiral track along the disk similar to a record groove."[45] This has led some to compare it more to a "tape-stream" unit than typically what is thought of as a random-access disk drive. (wiki)

Highly interested, I'm not a technician, but would be pleased to help if I can, cheers !

I don't know about the others, but the Thomson floppy controller seems to handle QDDs pretty much like a single-track floppy.
http://www.alternative-system.com/specific/emu/jteo/discs/FromP200/to8/to8v2/docs/MT_TO8.html, part 3, section 9 hassome information in french.

* No STEP command
* No motor ON
* No index pulse

But the THMFC1 is a custom controller, it may be doing many things differently when a QDD is detected.

Just to bump this up a bit... Working on a floppy emulator for 10 pin Quikdisk drives could be quite profitable I'm sure. I've seen devices that use these rare drives just tossed into a skip before (in this case 8 Akai X7000s thrown out by a university). A floppy emulator could be their only hope.

I can't speak for other devices but there are plenty of X7000 owners (well, me for starters) out there that would love to keep a library of samples on one SD card. They're a decent quality keyboard and the sound is gritty and punchy. Nice simple interface too.

Anyway, to those that have the knowledge of floppy emulation, you could save countless mid-eighties samplers and game consoles from total destruction by emulating this obscure format....somehow.
