Absolutely. I have lots of fun restoring old machines; it's one of my favourite hobbies. Not only do I get a nostalgia kick from remembering systems from my younger years, but I also learn a great deal about how they worked internally and about electronics. Once they're fixed, I lose interest and move to the next project.
Portugal has no electricity as we speak. Funny enough telcos and 4G/5G are fine for now, I'm guessing batteries and diesel backups kicked in and are doing their job.
yeah you're both right, WCS is on the main board in PAL machines, but not the Kickstart ROMs. I got confused because when I finally fixed the issues with the CPU socket I already had the Parceiro plugged in and it injects Kickstart on boot from the SD card. I'll edit the blog.

Author here. Thanks, had a lot of fun! Not sure why the original post from a few days ago didn't merge with this one, it's the same url ¯\_(ツ)_/¯ https://news.ycombinator.com/item?id=42832032
The Z80 and the 6502 (well, 8502 actually) CPUs share the same bus, and so there can only be one CPU running at one point in time. However afaik in CP/M and Z80 mode there are some I/O functions for the keyboard etc that halt the Z80, switch to the 8502, do what they do, and then switch back.
I'm not sure if you can somehow programmatically switch from the Z80 to the 8502 and back, though. I suspect not.
