While cleaning out my garage, I found a box marked "engineering stuff" which contained a second black and blue box marked HP-65. Much to my suprise, it contained my HP-65 along with the whole anchalada, sales slip and all. It was purchased in June, 1976, and used until 1982 when I replaced it with a HP-16C.
It appears to be in excellent condition, and the battery pack holds a charge (3.96V, unloaded). However, when I try to download a program I feel opposition to the mag card and the card reader motor makes a loud squealing sound likes it needs to be lubricated. Can anyone send me a set of maintenance instructions including the type of lubricant and the lubricating points? Once I correct the problem, I will run a full diagnostic. I think there is a very good possibility that its fully functional.
