Hi,

Looking for EPROM images for the Memorymoog, version 2.5. I could find and burn  
the three EPROMs with the 2.4 firmware version, but no luck with the 2.5. Does anyone have  
these available?

Many thanks!

Hello, I don’t have the files, but I have some chips if you wanted to go directly to the chips. You can send me a PM.

Hi, I too am searching for Memorymoog firmware v2.5 (either files or EPROMs) to do the autotune upgrade. Did these ever surface? Thanks, Russ

Don’t bother. Except for two dormant bytes at the beginning of one of the EPROMs that only change the checksum, they’re 100% identical to 2.4.

@[solitaire](https://solitaireio.com) I haven’t seen the 2.5 EPROM images available online. You may have better luck asking in Memorymoog or vintage synth forums—someone might have archived copies. Good luck!
