My Gotek comes soon, i can test it and then sell it to you for 30 Euros (excl shipping.) Because my disk drive is in bad shape (the button fell off and has trouble staying in place, no idea if that can be fixed or.)
if the Gotek works i can sell the original disk drive, i think 10 will be a decent price (It says 07/90 on the front of the drive, however my Amiga has a red light and a heatshield in place so i could not check whats under it.)
