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.



New EEPROM, not old stock. Install instructions sent via Reverb messages after purchase. Over a dozen sold to very happy buyers!!!!

Please back up your custom data before installing since if you're upgrading from a very old version, you might need to factory reset your MR61/76 (hold Song Erase button and turn on the power.) The vast majority of MR61/MR76 have a new enough OS B and OS C chip to run this. Some very early MR61/MR76 need both B and C chips upgraded or it will not boot but this is extremely rare.

MR Rack latest OS is 1.53 and is a dual ROM set. I have the MR Rack OS chip for the same price in a separate listing.
