So for example, pin 2 of the organ connected to pin 8 of the emulator becomes pin 25 on the organ connected to pin 8 on the emulator and so on. If you have a 26 pin connector on the instrument you'll have to translate the pins. Warning: The wiring diagram below refers to the original, 24-pin pinout. The pinout differs, here is the newer, 26 pin pinout: Pin number
This one had 26 pins instead of the 24 pins the original one had. Newer pinoutĪpparently the original floppy drive was discontinued and Technics switched to a newer model later on.

The pin names are taken from the official service manual for the organ. Side of the floppy for double-sided disks Indicates whether the drive currently is aligned on track 0 Indicates the index hole in the floppy disk Pin numberĬould be Disk Change, but is not connected on organ side The pin numbers 1 and 24 are written on the PCB. I changed the jumpers and connected my adapter the right way and it worked! Pinout of the organ Older pinout Apparently it is possible to do some minor configuration on there, like setting to emulate drive A or B and whether to generate a proper READY-signal or not. Nearly a year later, in February 2016, I searched the internet again and looked at my adapter and the emulator and noticed that I had the wrong jumper settings on the emulator. It was not that important and I could live without a working disk drive in my organ for the moment. So I tried around for a bit but still couldn't get it to work. None of them were explained in the service manual and apart from the name of the pins I had no more information. As you can see in the pinout of the organ I have 2 unknown pins.
I designed a small adapter with a few extra pin headers so I could experiment and rewire them and installed that too.

I guess that's ok as I don't intend to install a floppy drive again, and even if I had to I could unsolder it without damaging the board. I had to solder directly to an original Technics circuit board (see images/my_adapter). To do that I had to get the service manual for the organ and a cheap USB floppy emulator (I got a GOTEK SFR1M44-U100K-R).Īs stated, the original drive is not connected through a standard floppy cable but a flat flex cable (see images/floppy_drive) which I could not get a connecting plug for, so I did something I did not want to. As getting a replacement drive was expensive or impossible I decided to install a floppy emulator and build my own adapter. The floppy drive in my Technics GA3 broke and any good disk I put in there was unreadable after it had been written to. This repository contains the information needed to build such an adapter. It is possible to build a fully-passive adapter that connects the emulator and the organ. Fortunately, the organs used an interace that is logic level compatible and even uses most of the same pins. Therefore standard floppy emulators can not be used in these organs without modification.

The Technics GA-series used special floppy drives that did not use the standard IBM PC or Shugart connectors.
These emulators are also faster in some cases as they usually don't produce read errors as opposed to regular floppy disks. This fixes some of the problems, like reliability and data safety. ) but provide the same interface to the device as a floppy drive. Because of that, there are efforts to replace floppy drives with emulators that use other media (USB drives, SD cards. While floppy disk drives in musical instruments are still used, sometimes even in brand new ones, they do not provide the reliability, speed, data safety and convenience expected nowadays. They were originally equipped with a floppy drive that could read and write 2HD and 2DD 3.5" disks. Even today, they are considered very good instruments by many musicians.
