These are the LAST ROM chips for the Ensoniq EPS, and are required in order to run the new SCSI2SD boards. They are 2.40 for the EPS keyboard, and 2.41 for the EPSm Rack.
Comes with the two chips necessary for you to open up your board and replace the older versions that are already installed.
NOTE: This does NOT apply to the EPS 16-PLUS, only the Original EPS.
