@koaftder:
Don't kill an innocent old A1000! Even if it doesn't work, stick it on eBay and someone will buy it, giving you a few $$ and someone else some fun repairing it!
I made the mistake as a kid of trashing a few Commodore calculators (bought for next to nothing at a second hand sale in the early '80s) and I really wish I'd kept them now!
