the battery would be almost exactly in the middle of the main board. It won't be on the back.

Thanks,
 It didn't seem to have a battery visible
though It may  be on the other side of the main board?
I didn't disect it too much last time I had it open, other then realizing the regular battery compartment and connections were toast.

I'll try make time to check it out further later this week and get back to you.
Again, Thanks

Hi Rob,

Welcome to the group.

Replacing the backup battery is easy even for someone that has only limited experience with a soldering iron. If you take it to a tech then it should be quite cheap to do. The only thing that complicates matters is that some of the early Poly-800's came out without any solder tabs on the main PCB where the battery is supposed to be soldered in.

1) If you already see a battery present - no problem.
2) If you can see the battery solder pads in the middle of the main board - no problem.

But, if you can't see the solder tabs let us know because we can put together a simple document that will describe what needs to be done to fit a battery.

Mike

Hi ,
Just sending along a not so short e-mail,
to confirm my membership.

And So.....
My recent acquisition, an old  poly 800, isn't modified( as of yet anyway),
but It seems to basically function OK, dispite a few shortcomings.
I need to get a new battery set up for it .
The internal battery  probably needs to be replaced at this point?
 Also the regular battery compartment, ..the old C batteries, must have leaked all over the place, as I found the" C "battery compartment and it's minuscule connect at the board are presently toast...not much other major damage done as far as i can figure,(hopefully)
other then some rusty spots here and there on some metal supports inside..

I am able to change parameters etc, and the tape in works,
 though I have not tested the tape out yet..

I had read somewhere on the web, someone had adapted a cordless phone type- rechargeable battery pack to their poly.. instead of the old C s.,  and  that would seem a  very cool idea!

I'd really like to do something, as I hhear that without batteries,  I am unable to store anything I've created on it when I power down, and  it seems to take a while to build sounds that are to my liking..

 I could attempt to use a tape back-up every time I turn it on and want to get my settings back but that doesn't seem like it would be all that spontaneous and seems a bit of a bother.
For right now, it's a very interesting workout in making cool sounds..
and I've found some sound files I'll be able to load and check out,
but I have hopes of it being more funner if I can get it working at least asit should
and with other possible modifications .

Working on a major repairing/ modifying of this thing myself would seem a poor choice..
as reading  schematics is a little over my head and
working with tiny circuits and a soldering irons is not really my strong suit,
as I have the eyes of Mr Magoo, (plus I am a bit ham handed)
So  I 'll probably have to send it out to be worked on.
Hopefully  I can  find someone that would be able and want to taclke
 an old troubled poly 800.
(I can't even find someone to comptently  fix my poor old car's horn )

I would welcome any sugestions, ideas or useful info in these regards.

Thanks!
