My original HP-25, ailing

[teenix]

I think it would be worth trying to fix. If you sell it, once it's gone it's gone, and you might be left with that nagging feeling, I wish I kept it. Besides, even if it is not working now, it may get a touch up in the future, and sitting idle in a cupboard doesn't cost anything.

It might be something simple like a failed capacitor in the power supply, or something worse like a failing ROM or ACT. Check for signs of corrosion and clean, you may be surprised.

You could search "cleaning woodstock keys", and get some hits.

I'm probably a million miles away down under, but I would have been happy to give it a look over.

cheers
