<daddy>howdy o/ thought i was still in here, i was not.

<daddy>oriansj: are there any plans for a new stage0-posix tag soon? i'm trying to update live-bootstrap within stagex and it needs a newer stage0-posix for unxz that has yet to be released

<andydude>Can I help?

<Guest50>Hi, I found the stage0 project, which sounds very interesting

<Guest50>The readme says, under "Future dierctions"

<Guest50>> Hardware

<Guest50>> Implement the Knight processor in FPGA and then convert into TTL.

<Guest50>What is meant by "TTL" here ?

<Guest50>I guess it's not just the transistor-transistor logic technology, e.g. as opposed to CMOS

<Maja>i assume shit like the 74xx logic series

<Googulator>It needs to be something doable without modern lithography equipment that itself relies on firmware and modern lithography for its own existence

<Googulator>Bootstrapping lithography would be a formidable challenge, mainly because virtually all relevant lithography techniques are proprietary and trade secret

<Googulator>Achieving 6502 or maybe 80386-level performance is the "easy" part - going from there to something with Intel Core 2-level performance is the more problematic task

<nikolar>i mean there's like 7 orders of magnitute between 80386 and core 2 transistor counts

<ekaitz> https://www.meetup.com/guix-london/events/303448758/ <--- i'm talking about the bootstrapping effort for riscv in guix london in 30 mins

<aggi>Googulator: and it's not desirable to do it for modern monstrosities of what's sold ax x86/64 nowadays

<aggi>64bit in general seem a little unrealistic, because an intermediate FPGA deployment is either expensive or not feasible

<aggi>a 32bit x86 however, this would be great if such existed, fully opensource with permissive license, without relying on proprietary tools

<nikolar>i am pretty sure 32bit x86 patents have expired

<nikolar>so sounds like that should be perfectly doable

<Googulator>IIRC the original patents on AMD64 also expired in 2021

<nikolar>so you could even create an x64 chip

<nikolar>nice

<nikolar>that even include sse2 i think

<Googulator>yeah, SSE2 definitely was on the market in 2004 already

<Googulator>so it should be expired too

<nikolar>sse2 is part of the x64 spec

<nikolar>you can't really have x86_64 without it

<nikolar>i am just not sure which version of sse it was
