Sequential Circuits Prophet VS 1.2 high and low OS ROM firmware set

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.

This is the latest OS released for the VS.  These ROMs are pressed to an ATmel ROM manufactured in the last year, ensuring it will last for an extremely long time.
