Where can I find and download a very old firmware? I want to downgrade to version 7820 from 2015 or even 6975 from 2014. All firmware versions used to be available on hpcalc.org, but I can't find them now.
I believe I've detected a significant bug that greatly affects performance, but to be certain, I need to revert to an old firmware version (I hope my HP Prime will survive this) and then run some tests on physical G1 hardware.
