RE: HP25C sad story, need opinions
BTW, I just used the procedure I described above to resurrect an HP-21. Battery corrosion migrated to the keyboard. 100% DeOxit in the holes. Set for 15 mins. Scrub with stranded copper wire in the hole rotating as much as possible to get around the inside of the contact area. Flush with 5% DeOxit spray, then compressed air. I now have an excellent HP-21 for $33 plus a half hour of my time.
