IBM S/390 Multiprise 3000 Mainframe - Part 2: Replacing the Support Element clock battery.
Another rambly video, this time regarding the built-in clock battery required for the Support Element SBC to make the BIOS changes persistent. My next goal is to back up the custom OS/2 software required to IPL the main processor. Unfortunately SSA has very limited support, same with OS/2 HPFS file system making the backup process more complicated.
