Ensoniq SQ-2 battery & Rom card

HELP!HELP! I NEED TO LOCATE A BACKUP BATTERY FOR THE SQ-2 NOW!!

I AMY GETTING A "LOW BATTERY WARNING" AT POWER-ON AND I CANNOT RETRIVE MY SEQs OR SONGs TO EVEN MIDI THEM OUT.

ALSO, IF YOU KNOW WERE TO GET ROM CARDS FOR THAT MODEL AND ANY OTHER SUPPORT ITEMS IT WOULD BE A GREAT HELP BECAUSE THERE IS NOT A LOT OUT THERE FOR THAT MODEL, NOT EVEN AT ENSONIQ

THANKS - HELP! HELP!!!!
