⚠️ CAUTION!
It's OK to boot/use your compact Mac with the case-back off, but DO NOT work inside it while powered. No need to discharge the CRT for Fat Mac Switcher installs, but DO NOT touch the back of the CRT. Power off, then disconnect the motherboard carefully such that your hand won't fly upward and break the CRT yoke (not repairable). Toggle Fat Mac Switcher only while powered-off. Be Safe, and Have fun!
