Ensoniq SQ-80 OS v1.8 EPROM Firmware Upgrade SET [with Hidden Waves enabled]
  • This version 1.8 is the latest firmware update issued by Ensoniq for the SQ-80.
  • Included will be 2 brand new ATMEL EPROM chips to complete the upgrade.

Please note: The SQ-80 is not for sale, only the EPROM upgrade chips will be supplied.

  • The “hidden waves” firmware revisions are a modification made to the stock 1.8 firmware to enable additional hidden waveforms. You will notice WAV075 to WAV255 are now enabled.
  • In my opinion, they are somewhat glitchy and circuit bent sounding, which make for interesting and creative sounds.
  • The KPC / Keyboard Processor Circuitry EPROM is not included in this listing. Most SQ-80’s tend to already have them installed. On the off chance that you do not have KPC ROM 1.50 installed, send me a message and I’ll help you out.

If requested - A link will be e-mailed to you with the SQ-80 service manual for your own personal reference. I find this to be quite useful and informative

ALL EPROM upgrade chips and components that I provide here are in fact brand new, high grade, recently manufactured and sourced directly from ATMEL. Using new-age flash technology is the best way to ensure that the data integrity of your upgrades last well past our natural lifetime.
