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.

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.

I still have it in a closet. It booted up about ten years ago, but I'm afraid to power it up now without taking a look at all the capacitors.

I was surprised that the capacitors and the motherboard in general on my A1000 looked so good ~35 years later. Either way, yes, replace them.

Well, kind of.

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.

Sending you on a train to nowhere in deep Douro wasn't enough to prevent you from returning.

I hear this so much, sometimes in the most unexpected situations, and it's heart-warming. One day, I was having lunch with the family in a remote place in a restaurant in Serra da Estrela, and a random folk came to the table just to tell me how Codebits had shaped his life. I think I shed a tear righ there.

Anyway, yes, we have to find a comeback angle someday.

oh, wow, Hacker News. Inércia 2023 was raw and pure; I loved it. My post is just a tiny POV fragment of many other things that were going on there. I hope the team organizes Inércia 2024 because I'm already dusting off my 6510 assembly skills to work on a demo for next year.
