On the bottom theres a battery compartment that takes standard AA batteries. That's what retains the pattern memory.

Check out the TR-707 Yahoo group. There is some info on modding it for custom sounds there.

Hi All,

I have a Roland TR-707 with a scrambled memory problem. Should I
assume the backup battery is shot?
I can program patterns in but after powering off and on again all
pattern locations have every beat filled with hits of every single
drum sound simultaneously. Sounds delightful too ;-)

Also, does anybody know of any active projects involving custom sample
ROMs for this drum machine? I found something like this for the TR-626
and was hoping perhaps there was a 707 project along these lines that
might be too new to be easily found with Google. Any ideas?
