@neauoire I can't thank you enough for sharing this! I have been waiting for years for the Z80 homebrew community to get past its obsession with CP/M. This is the coolest thing I can possibly imagine having come along to answer that wish! If this plays nicely with machines with ROM at the bottom of the address space (which it sounds like it *should*!) I'm definitely going to give it a spin...
@solderpunk 👌 I'm glad I could help. I'd love to see your experiments with this.
@xj9 @neauoire I am very open to the idea that the Z80 is not the best platform for this project, or even that this project's hypothetical scenario doesn't make a lot of sense. I'm just very excited because (i) I've designed and built a Z80 machine before, and know the asm, (ii) I've been quietly wondering about a salvaged-electronics future for years, and (iii) my hobby electronics has been in a rut for years waiting for "worthy" project ideas.
@solderpunk @xj9 @neauoire Whereby "worthy" I mean "project ideas which acknowledge that electronics manufacturing is energy intensive and environmentally destructive and even if 64 bit ARM CPUs are dirt cheap and ubiquitous and don't use a lot of power to *run* (once made), it's still kind of insane to treat them as limitless and disposable, for trivial purposes to amuse oneself or satisfy some idle curiosity".
> preserve our ability to program microcontrollers through civilizational collapse.
This sentence fragment can be interpreted in two ways...
What I want to know about is the ability to fab wafers after the collapse.
Good research project to see the smallest architectures one could fab at home now.
We need to be able to make z80s.
and maybe hedge in some simple ways (like trying to record general knowledge in a resilient way for people to access in the future)
i don't know about trying to build microprocessors in a post-apocalyptic bunker. i'd probably have bigger things to worry about, i dunno.
@gendor i think i would be spending my time trying to help rebuild society so that things could be manufactured again, instead of trying to build one or two of my own in a basement before running out of supplies
@gendor but, like i said, i think this is still cool and a good idea to prove and show how it can be done.
@gendor i think being able to show that processes can be replicated and have the knowledge transmitted to other people and understood is really important
