About This Listing

Roland S-550 OSv2.00 Firmware Upgrade EPROM SET
  • OS v2.00 is the latest and final operating system issued by Roland for the S-550.
  • Included will be new 2 EPROM chips, which will be labeled accordingly to indicate which IC socket the EPROM is to be installed to
  • The OS v2.00 upgrade contains several bug fixes, improved stability and finalized system code optimizations.

Keep in mind that the S-550 itself is not for sale, only theEPROM upgrade chip is.

Please Note: Early S-550 revisions come with removableEPROM sockets and later S-550 revisions have the EPROMS soldered directly to theboard. The later S-550 revisions already have 2.00 installed so no need topurchase this upgrade. 

To check the currentfirmware version installed on your S-550:

  • First - a monitor needs to be connected to the RGB port of the sampler
  • Power on the S-550 while holding down the [1] button located on the DATA ENTRY keypad.
  • While holding down the [1] button until "Please Insert System Disk" is displayed, insert system disk v1.13
  • Still holding the [1] button, wait for the disk to load and count down from track 80 to 0 and then press the [DEC/NO] button when prompted with the “Next Disk Please” message.
  • You’re not done yet.
  • Press the following buttons in exact order [FUNC] / [MENU] / [ DOWN ARROW ] / [EXECUTE] / [MENU] / [1] / [DEC/NO]
  • After all of that, the following message should be displayed:
    Ver # disp     MT25 ROM. Ver. 2.00 11 SEP/87     S-550 SYS. Ver 1.13 26 OCT/88
  • Pat yourself on the back that you lasted this long.

Besure to take note of the marked orientation notch on the side of the EPROM toensure correct installation. EPROMS inserted backwards will be destroyed.Incorrect insertion of ICs is also likely to cause damage to the board.

Rest assured that all EPROM upgrades I send are packaged in antistatic reusable packaging and inserted into a bubble mailer.

I send allinternational packages via airmail parcel in order to ensure that your EPROMSarrive safely and in a reasonable time frame. 

Purchase withconfidence!
