UPGRADE YOUR ESQm TO THE REAL SQ80M!!!
Dozens & dozens of very happy customers all over the world!
BUYER RECEIVES REPLACEMENT OS ROM, REPLACEMENT WAVE ROM & AN ADDITIONAL CHIP. A few feet of wire is also included.
I have performed this upgrade to several ESQm's of my own and many units for customers. This upgrade kit is very well tested and is an easy upgrade to do with moderate soldering skills needed.
The latest guide, which I last updated in Feb. 2020, & wiring diagram will be included with every purchase (also available as a PDF with a google search for "sq80m guide").
If you need a new battery too, please see my other listings, I am very happy to combine shipping for you. Also, replacing the battery during the upgrade process eliminates the need to perform a system re-initialization after installing the new chips.
If you have any trouble during the install process, I know this upgrade & its quirks very well & will be able to help you get your issues resolved quickly & easily.
But you do have to be able to solder, or know someone who can. I can not be held responsible for damage to your ESQm etc.
Why buy your ROM from me? I was the first to sell strictly brand new, newly manufactured, made in USA ROM chips, in a proper ESD certified environment. I only use OTP ROMs which are impervious to bit rot (data corruption!) I was not afraid to say this even though I knew others would realize the gig was up on selling recycled, quick-to-fail EPROM's. I am an AMERICAN BUSINESS who only sources my stock directly from other AMERICAN BUSINESSES - this means your purchase keeps our local economy going.
Not only am I shipping from within the USA same or next day, offering the best prices & lifetime support, I also am the ONLY ROM seller in North America paying royalty fees on every sale where it applies, and the ONLY ROM seller who has 10+ years of formal synthesizer & pro audio repair experience.
THANK YOU and never hesitate to write to me with any questions or concerns!!
And of course..... Free 30 day returns. No hassle, no problem. Instruction guidelines included. Thanks for looking =)
--- Shipping & Handling Update ---
Please note as of November 6, 2020, my city has enacted new lockdown protocols & curfews. I have increased my shipping handling times to 3 business days to allow for additional delays which may be incurred due to these new regulations. I will continue to make all efforts to ship within 1-2 business days as I usually do, but please understand if it takes me up to 3 business days to get an item shipped. Thank you for your understanding and thank you VERY MUCH for your business and interest in my products!!!
