     DIRECT FROM ROLAND DOCUMENTATION
             The Roland CD‑5 is the only CD‑ROM drive known to work with the S‑550. It used a Sony CDU‑xxxx mechanism with a removable CD caddy
             The CD‑5 came with a CD‑ROM disc (Roland P/N: L‑CD1) which contained the (nearly complete) S‑50 and S‑550 RSB Sample Libraries

  [1] The Roland CD‑5 is the only CD‑ROM drive known to work with the S‑550. It used a Sony CDU‑xxxx mechanism with a removable CD caddy
  [2] On the back of the mechanism next to the 50-pin SCSI connector, the columns labeled 'BLOCK' and 'PARITY' should be jumpered
  [3] 11-pin SIP Terminating Resistors socketed on the PCB may have been removed at the factory or by a previous owner. Verify if these are needed for the SCSI chain
  [4] Device is recognized by the S‑550 and W‑30 but locks up the sampler and/or displays a "HARDWARE ERROR" message when trying to access a CD during any LOAD operation
  [5] Works perfect when loading sample data CD's however, it does not play audio CD's from the sampler menu. The message 'ILLEGAL REQUEST' is displayed
  [6] This model loads sample data CD's with the S‑760 but the ability to play audio CD's from the sampler menu has not been tested extensively. See Footnote [17] below
  [7] This model had factory installed firmware v1.8g
  [8] To test this device, it was installed inside an AppleCD 150 external SCSI case)
  [9] Along with the 'BLOCK' and 'PARITY' jumpers, the 'TERMINATION' jumper should be set accordingly. See the settings at this link
[10] Device reported by online visitor as NOT WORKING with the S‑550 and W‑30
[11] Device reported by online visitor as WORKING GREAT with the S‑760
[12] Device reported by online visitor as WORKING GREAT with the W‑30
[13] The Toshiba TXM3401E1 was used extensively in the 1990's to install the IRIX O/S on SGI Supercomputers, Servers & Workstations (Origin 2000 / Power Challenge / Indigo)
[14] Nakamichi models MJ-4.8si and MJ-5.16si will only access one disc (CD #1). Using multiple CD's is not possible.The 5-CD changer mechanism only operates via computer software
[15] There is no guarantee that if you find an internal Sony mechanism and install it inside a generic external SCSI case it will be compatible with the S‑550
        Most of the info I've read on the Internet shows that the only CD‑ROM compatible with the S‑550 is the CD‑5. By looking at inside a CD5, you can tell it's customized
        Off to the side of the mechanism is an additional SCSI board unlike a normal external Apple CDROM

[16It's unknown if the W‑30 will function at CD‑ROM speeds higher than 4x. The highest speed mechanism I have personally verified is 4X using a Plextor Model: PX‑43CS                  
[17] S‑760 O/S v2.19 through v2.24 has seven additional CD-ROM drivers accessible via menu SYSTEM MODESCSICDP TYPE. Detailed documentation is here




     Caddy Malfunction Info
* Caddy Eject Malfunction
Some AppleCD mechanisms will stop working because they continuously eject the caddy. Over time, defective capacitors on the logic PCB will start to leak. This is a very common problem with Sony CDU‑541 mechanisms and similar Sony mechanisms. AsteronTech has put together a detailed repair guide for replacing the nine defective capacitors. Note: The replacement guide at AsteronTech uses ceramic capacitors in place of electrolytic capacitors to reduce the chance of capacitors leaking in the future. I'm traditional and prefer to use components exactly as shown in schematics. I have compiled a list of mouser.com parts which are exact replacements here

     [sgroup] S550 and SCSI supported drives
     Date: Fri Oct 4 14:05:54 EDT 2013

          I've spent years looking for CD ROM drives that work with the S-550.
          I was strung along by computer salvage yard guy who swore he had one, but had to find it again.
          I kept offering him premium price to spend the time. No dice.
          I finally bought early all single speed SCSI drives off of EBAY and checked them out
          but very little success. The problem is people get very little money for them so chuck them out.
          The one that I found was from a school in Canada.

          Here is what I found:
          The AppleCD 150 is almost impossible to find and I have no experience if even the 300 works.
          The 150 should work but good luck finding them.**
          The Sony CDU-6111 definitely works. I found a CDU-6112 that worked.
          It eventually failed and I tried to fix it by replacing head but couldn't.

          All others that I bought where the numbers were close but were not compatible.
          Most sellers don't advertise the model numbers, but you got to look for a Sony single speed
          SCSI early model, and, if, an external drive, it would be part of a "caddy" system.
          In the end my S-550 had the hard drive, 4CD's but a broken CDU-6112.

          Now I have (3) S-760 and I file convert all the S-550 CD's from a CD I bought off of EBAY.


** Editors Note: I have tested an AppleCD 150 with Sony CDU‑541‑25 mechanism + factory firmware v1.8g and it is NOT compatible with the S‑550
