Ensoniq EPS

Released in 1987

The Ensoniq EPS is a 13-bit digital sampling keyboard which saves sample data to DS/DD floppy disks. It's sample memory can be expanded by installing either a 2x or 4x optional memory expander. An optional SCSI kit was also available, but the SCSI implementation was fairly rudimentary, and the EPS is unable to recognize CD-ROM drives or Zip drives.
