I usually buy NiMh replacements for the NiCd cells in the old calculators I have, often from ebay sellers. Take a look at ebay item number: 5960800976 for example. The Summit calculators are very hard to open. A few models have a center screw hidden under the back label, but most don't. Sometimes you need to really dig deeply into the edge seam with an X-acto knife to get them open, in other cases you can squeeze them the top (or bottom) half of the case from the side to help get it apart. They designed these to never be opened, unlike most other manufacturers that realized that nicads might need to be replaced.
