!!!!! This is for the ESQ-1 only
!!!   The SQ80 and ESQm have different firmware versions, I also have them listed. I recommend watching the attached Youtube video for an explanation of hidden waves.

The only EPROM store promising to ONLY use brand new, newly manufactured chips! Don't pay for 30, 40 year old re-programmed chips that will suffer from BIT ROT when you could get brand new ones. Yes I have the best prices and my chips are actually Brand New. I am also the only seller offering a 1 year free replacement on all my chips because I am that confident in them.

Will provide hidden waves unlocked ROM at special request. Please message me before ordering or immediately after ordering if you want this. If a message is not received within a few hours of ordering i will be shipping the official issue 3.5 ROMs.

This is a set of both ROMs (upper and lower) of the latest OS released for the Ensoniq ESQ1. Tested in a real ESQ. Works perfectly or your money back.

I do not re-use old, recycled EPROMs. I only buy new Atmel ROMs directly from distributors and program them myself.
