2=HP 82106A Memory Module Cartridges. 1=HP Hard Carrying Case for Modules.Just out of Original Owners Estate Sale! Can't test due to not having batteries or a power supply. WE were told these worked perfectly when he put them away years and years ago. Might have some minor scruffs, dust, etc. But overall in excellent shape. VERY little use, always inside the carrying cases and never abused.
