I recently received a Polaris as a gift. It had not been powerd up
in quite some time, and the batteries were dead. I think it has lost
its firmware. It makes some odd beep and bloops but the oscillators
are not functioning. Does anyone have any idea how I would go about
remedying this? I am, for all intents and purposes, a total novice
at synthesizer keyboards. Can anyone point me in the right
direction? Do I need to track down some new components or is it
fixable by flashing the bios?

eh, sorry about the username. I created this account when I was a
teenager and I thought the excessive stupidity of the username was
hillarious, or something.
