I have a good old TX-4000 from Mayflash, but the 9 pin cable that connects the pad to the control box is broken. I looked these up, found that they were called "DB89", but the cables I've tried aren't compatible with the device. I searched on a number of marketplace and forums, tried to send Mayflash an email, looked for the cable's pin-out diagrams, but couldn't find a solution so far. I asked somebody who works in electronics, and they told me the issue is that these 9 pin cables aren't wired the same way on the inside.
May you know where I could find the right one? Or even a full replacement control box?
Thanks much for your time,
