Hi Michael,

There isn’t really any easy way toput a battery holder in the normal place on those old boards. I usually put aCR2032 holder way over on the little board with 3 trimpots, over beside the Ccell holder. There is already one little hole drilled in it on the far side ofthe trimpots. I just measure the right location for another hole, drill it,stick the battery holder in and bend the solder tabs so it doesn’t fallout. It needs to be a very, very small hole. So, here is how I do it:

 

1 – Remove the main board.

2 - Remove R1 and D1 (in the corner nearwhere the A/C adapter plugs in).

3 – Remove the little board with the3 trimmers and drill another hole for the battery holder.

4 – Put the battery holder in andsolder black and red wires to it. (red is positive).

5 – Attach the other end of thewires to the holes where D1 came from. (red near the edge of the board andblack near the “D1” label)

 

Stick in a new CR2032, reload yourpatches, and you should be all set.
