![]() ![]() I'll keep updating and expanding this page from time to time. This support page is work in progress, and any corrections and updates are welcome. They also require a system diskette to boot up, and they can be hard to come by, so most non-functioning units are actually just working units with misplaced boot disks. The reason for this is because they they're usually found non-functioning. Nowadays units can be found for less than $100. When the Roland MV30 first came out, it sold for around $2000. It also has two SN-U110 ROM card slots which can be used to expand the available sounds of the system. For expandability, it has a 720 K floppy disk drive. Quick Disk drives were also available for some mid-1980s home computers such as the Sinclair ZX Spectrum, the Dragon 32/64, and the Sharp MZ-700 and MZ-800. This unit came with a built-in sound bank which includes some of the most famous sounds from Roland's 80's era synthesizers, and some percussion sounds, including some from the well known and respected TR-808 and TR-909 drum machines. The Quick Disk was used in some MIDI keyboards, samplers, sequencers and drum machines from manufacturers such as Roland, Korg, Akai and Yamaha. The Roland MV-30 is a portable music production system and has built-in midi sequencing capabilities (one of the earliest ones). I probably will end up trying this at some point if I manage to find a regular QD disk for cheap.I decided to open up this small support site for the Roland MV30 because I found that there was little information on it on the web. I can confirm FD7201P can not be swapped with FD3206. Quote from: undefinedFDS 3602 ? You mean FD3206 ? I'm thinking motor sense may be hooked to the positive terminal on the motor itself? Not sure. Sports DCT (Photo: Honda Motor Company) Quick access to motorbikecatalog website. Will have to try to see what sort of readings the batt/motor sense pins give out. Spoke wheels were used with a front and rear single disk brakes. Well, naturally, the idea would be to make the adapter so that it can be put into a regular FDS, power board, and all. In the Roland the disk drive probably receives power directly from the main unit, but the Famicom's AC-adapter is most likely not beefy enough so Nintendo built a separate power board in the HVC-022 unit. ![]() Quote from: undefinedThe battery/motor sense pin is probably part of the power board of the FDS disk drive unit (HVC-022) which provides the power to the disk drive, and allows the software to know if the motor is on or not via this pin to the RAM Adapter. The disk is difficult to insert, as well, as if it was too thick. Regular FDS disks do not fit and the carriage just refuses to lower. Roland's S-50 and S-10 samplers were on display The larger S-50 features 16. Yeah, the only thing stopping me from doing this is the fact I've no disk to try it out with. 5-inch disk drive, pre-output equalizer, and twin digital delays on its.

I have been looking at QD-drives for MSX just for the heck of it but they have been a bit too expensive to pick up without a good enough reason, besides the disks are also not so common. If you were to use the Roland drive with an FDS RAM Adapter you would also most likely need the power board to power it. The battery/motor sense pin is probably part of the power board of the FDS disk drive unit (HVC-022) which provides the power to the disk drive, and allows the software to know if the motor is on or not via this pin to the RAM Adapter. I have no idea if the 3602 is pin-compatible with the FD7201P, but guess it could be possible if the 3602 is just Nintendo's ASIC containing a modified FD7201P to disallow full disk writes. I'm have no idea if an FDS disk card can be read and written in a normal QD-drive, but if it can I guess it might be possible to use this drive in an FDS (and in that case any QD could be used with it). The fact that the FD7201P drive chip is a stock Mitsumi drive chip seems to fortify this guess, and I know that other systems using QDs uses the exact same density as FDS disk cards. I would assume that the FDS disk drive is really just a stock Mitsumi QD-drive with a few simpler modifications to disallow disks without the FDS disk card shape and to disallow full disk writes. Second, that's a pretty neat find! I have been looking at QD-drives for MSX just for the heck of it but they have been a bit too expensive to pick up without a good enough reason, besides the disks are also not so common. First, I'm sorry to say that I don't have any of the answers you seek, just my thoughts and speculations. ![]()
