RE: HP-21 Disassembly Help...
Aaaaarrrrrrgggggghhhhh!
Gues I better finish the book. Pm sent Jeff! This requires Solder removal! No mods need be taken on the calc for it to accept alkaline batteries. The only mod is to the battery holder. Remove the middle spine and the batteries will be replaceable. This happened to a 19c, had to remove the solder to expose the original battery contact rivets. Geoff |
