These are instructions on upgrading Roland MC-300 MIDI sequencer from 1988 with Gotek USB floppy drive emulator. The method works with other Roland equipment such as W-30, S-50, S-330, MC-500, MC-500 Mk2, XP-50, SD-35 which utilized identical 720KB Shugart drive controller. SB-55 although electronically compatible, has a drive bay design that makes installation of Gotek impossible without structural alterations. Disk images presented in this tutorial for MRC, SMRC and MRM operating systems can be downloaded individually off Roland's website.All you have to do is rename .OUT files into "000.IMG, 001.IMG, etc" and place them inside IMG720 folder on your USB thumb drive. http://www.rolandus.com/support/general_apps_tools/ Or you can retrieve the entire pack using the following link: http://www.enilenis.com/projects/mc300/img720.zip Special thanks to Keith Meiere for offering technical advise: http://llamamusic.com/s50s550/DIY_page.html#usbfloppy Gotek SFRM72-FU-DL buying options: http://stores.ebay.com/e2WholeSale?_dmd=2&_nkw=SFRM72-FU-DL https://www.amazon.com/SFRM72-FU-DL-Floppy-Drive-Emulator-Gray/dp/B00C4PTOJM Worth mentioning that Gotek drive operates about 20% slower than a physical floppy drive.
