Kind of a somewhat silly question: I have several vintage mostly HP and some TI calcs. Do I need to say turn them on once a month or at some regular interval and go through a few key pressing in order to keep them in working condition?
The reason i ask this (not to put TI down or possibly it is precisely the reason it is a TI and not an HP)is because i have a TI-30 calc that was working say about 7 yrs ago. It has been in storage undamaged without battery for that long. It was dead when i tried to turn it on last month.
Thanks for any input. I guess we all need to know this if we are going to have our calculators outlive us (of course hopefully all of all us will live 100+ yrs? ;)
I keep all my calcs in their cases without batteries in a corner of my closet. Is that good enough?
Anyone else have any thought on storage to maximize longetivity and preserving working condition, please share. thanks
