Tutorial on how to modify Gotek Floppy Drive Emulator For a Technics SX KN-5000 Music Keyboard

This customization is only for Technics SX KN5000 Keyboards, for other models this will not work.

[@_PSantos]

Hi Thank you for your patience, great job. Got two questions, 1. Where do I get a Floppy Drive/UBS for my KN 5000 2. Where do I get a LCD Panel replacement for the KN 5000 Thank again Regards Paul

[@TECHNOLOGYTIPS101]

Thank you, so you can get the emulator on eBay just search for "Floppy Drive USB Emulator For Technics SX KN-5000" You can't find a new LCD Panel for this because Technics stopped making them, however keep an eye on eBay many people sell them for parts and you should be able to find it sooner or later.

@@TECHNOLOGYTIPS101 thank you for the reply. Do I need to have floppy in order to get the emulator to work? Sad about the lcd….. with out it, the keyboard is not as good

[@TECHNOLOGYTIPS101]

@@_PSantos No you don't need any floppy drive, but you must have the floppy drive connector cable inside your keyboard to plug it into this one. I know it's sad that Technics stopped making Music Keyboards because they had some of the best keyboards.

@@TECHNOLOGYTIPS101 totally agree with you, they’re still sound great! Again, than you for the info, and if by any chance you come across someone with a LCD that I can use…… if I get it to work I’ll see the emulator issue next! Stay save!

Hello, is it not possible to mount a regular Floppy Drive Emulator or do you have to specially mount the Floppy Drive Emulator for an XS-KN5000, John

[@TECHNOLOGYTIPS101]

Hi, You have to mount the specific one, or else it will not read. These emulators rage from $15 to $300 and the only difference is the firmware, and other customization such as OLED, encoder etc.

[@johnweetzel8633]

@@TECHNOLOGYTIPS101 I think it's quite a good price: $300, which is why I asked whether you could also do it with a general emulator

[@TECHNOLOGYTIPS101]

Do I do this mod if I bought the KN5000 emulator from you on eBay?

[@TECHNOLOGYTIPS101]

Yes, but if you want us to do it for you, we can do that at no additional cost. Also on some KN5000 by default you don't have to do this, our stock emulators work just fine. That is why we don't do it by default.

any clue sir for the position of the jumper on the SFR1MM44 U100K ? in my kn 3000....pls.. when i try to load any floppy numbers from 1 or above its will go back to 000 and gives error 02 and 09 on my kn3000 screen...guide me pls,....

[@TECHNOLOGYTIPS101]

It has to match the exact settings of the old floppy which was removed from the keyboard. There are 3 possibilities that you can set it to, and they are Master, Slave, and Cable Select. Most likely you need it to be set at Master. The manual of the Emulator should tell you which position is Master, and it should also be printed on the PC board next to the jumper pins. Thank you

The KN5000 wants to format the floppy every time. I have the SFR1M44-U100K emulator factory was MITSUBISHI M355F-3252MM will it work?

[@TECHNOLOGYTIPS101]

You need to make sure the Jumper settings on the Emulator matches the ones on the Mitsubishi Floppy drive. Also use the Windows App to format the flash drive to 100 banks at 1.44MB each Bank.

Are you sure your Technics KN2000 doesn't have a 26 pin drive?

[@asterix3542]

Dear Sir, Could you say if it is the same for technics SX-PR 250? It is also a 34 Pin floppy disk. Regards

[@TECHNOLOGYTIPS101]

Hi, The old Technics SX-PR 250 had three different types of floppy drives, and each one had a different configuration. Some of these configurations were controlling the drive jumper settings through the Floppy Drive Firmware and there was no physical jumpers on the drive. So in order to know which floppy drive emulator is right for you I need to know which model floppy drive your Technics originally came with.

[@asterix3542]

@@TECHNOLOGYTIPS101 The floppy drive is a model : SY-FD20!

[@TECHNOLOGYTIPS101]

@@asterix3542 Based on the manual this is a proprietary drive which has a 26pin controller board behind the 34pin drive. So it will only work if you take the controller board out and attach it to the new Emulator. See manual technicskeyboards.com/files/4114/1913/5359/sy-fd20_service_manual.pdf

It will really work? Someone tested it in Technics KN5000 ??? In my opinion GRAY wire in this video is soldered not to GND but to +5V line (!!!) ...

[@TECHNOLOGYTIPS101]

From my personal research it should be connected to Ground. The reason is that I took apart the original floppy disk that came with the KN5000 and traced down the wiring and all the lever switches to see what triggers the alert about floppy disks presence. If you don't do this modification the Keyboard may not detect the presence of the disk, or in this case flash drive.

[@wojteksz.8715]

@@TECHNOLOGYTIPS101 But on emulator you follow by trace +5V (not GND) and did solder GRAY wire to resistor on +5V line trace ... On emulator written GND on this trace but not relate to this trace - it just relate to 4 pin power connector pinup and means second pin.

[@TECHNOLOGYTIPS101]

@@wojteksz.8715 I double checked the video and you are absolutely right, the wires is connected to 5V. For some reason it is installed in my Technics KN5000 and it works great, so I guess it will work with 5V also. I am thinking the reason why it works is that there is an electrolytic capacitor next to it which is probably grounding the signal that way. So the verdict is that either option will work.

Hello Sir, also possible for Ketron SD1! Thank you.

[@TECHNOLOGYTIPS101]

Greetings sir, The Ketron SD1was originally manufactured with 4 different types of Floppy drives, and they are not interchangeable. Some of them came with a 26 Pin 1.44MB Drive, some with 26 Pin 720KB Drive, some with 34Pin 720KB, and some with 34Pin 1.44MB Drive. This will only fit those ones that originally came with a 34Pin 1.44MB Drives.

@@PakBudiTarigan the KN2000 has a different ribbon connector with 26 pins so you would need an adaptor to put the electrical connections on a 34 pin normal plug used in most PCs to the 26 pins used by the ribbon connector.

@@timpullen4941 Hi, Your unit was originally manufactured with 3 different types of floppy drives. So the bios on that specific model are programmed for the exact type of floppy drive which is currently installed in it. Even the pin count, connector type, interface layout and jumper settings could be different. So I have to know exactly which drive is in there now to tell you which emulator can replace it.

does SFR1M44-SUE work for keyboard?

[@TECHNOLOGYTIPS101]

That depends what type and version of firmware is installed on the SFR1M44-SUE. If it has the factory original firmware it may work for some keyboards not all. Specially if the original floppy drive was Mitsumi or Y-Data you will have a hard time with it.

It has to do with the type of floppy drive that is currently installed in your Technics SX KN3000 Keyboard. Not all of them had the same exact floppy drive. So if you can take out the old floppy drive from the keyboard and tell me what the model number is, then I can tell you if the stock SFR1MM44 U100K will work on it.
