In all truthfulness, I'm more of a software guy then a hardware guy. So, I need help with the maintenance for the 512kE. I want to give it a full overhaul (minus retro brightening and caps unless REALLY bad), so essentially, replace the internal batteries (CMOS, etc) and lubricate the floppy drive (since a disk is stuck in it). But I have no idea what to do, like how to de-electicify the CRT or get the disk drive out or the disk out . So please help. Thanks.
