The jury is still out of how much official this is, seeing that the legal situation for Genera is a quagmire. Wilder is that the MIT Lisp Machine branch is also being actively developed, and it has a clear legal situation today. To the point that there are several (simulated) CADR's on the Chaosnet talking to each other over the Internet. :-)

Is https://tumbleweed.nu/lm-3/ https://tumbleweed.nu/lm-3/ the project you're referring to?

  Yup! Feel free to prod me if you need help (forum, chat, mail ...).

    Someone needs to sell a Space Cadet USB keyboard (but with arrows).

      (I am slowly working on making a replica ... without arrows though)

        Is there any good literature on building keyboards? I’d love to try my hand at building vintage-like keyboards for things like DEC terminals, workstations (Xerox Star and Apollo Domain rely so much on their keyboards it’s hard to experience them on regular PC keyboards).

        I've just completed a keyboard inspired by the Lisp machine keyboards but aimed toward use on a modern Unix system. Making your own one-off hand-wired keyboard is time consuming but pretty easy if you can solder. I probably spent $400 all told, including a fully custom keycap set from https://fkcaps.com/custom/ https://fkcaps.com/custom/ I've been meaning to write a blog post about it but I'm still finishing shakedown (currently chasing a wiring problem that messes up multi-key chords on the homerow)

        No idea, this is sorta the project that runs on fumes right now. Wanna do something together? The keycaps are always the issue, making, remaking the PCB for the keyboard is just a days work even making it work with something like QMK or some Arduino thing. But then you want the keycaps, and each special keyboard has its own set .. double injection moulds are expensive unless you do a large batch.

        Sandpaper off the markings on a regular keyboard and write the keycaps with a Sharpie.

        That, or order blanks.

        > Wanna do something together? I know very little about keyboards (not much beyond reading a matrix, which is something I did once, 30+ years ago), but I’m in. I would imagine by now there would be a KiCAD wizard that would generate a standard keyboard with extra rows and columns if needed and all customisation would be dragging the switch footprints to their positions for the non 1:1 keys. Keycaps can be blank, laser eroded and resin filled, dye sub, or any other technique.

      Is this close enough? https://keymacs.com/ https://keymacs.com/

        Oh, man, I want one.
        lproven 2y ago
        Me too. I contacted the company. Turns out their address was within half an hour's walk from my old apartment in Prague. I thought I could at least try one. Nope. It's just a mailing address. Actually they are in a remote part of the country, at least 3-4 hours' travel away.

        Wow how cool, but $1,171 for the basic, non-soldered one? Guess it's not for the mass market...

        Horrendously expensive doesn’t count.

        Didn't you hear? Horrendously expensive makes it _better_. See: Rolex watches, Bugatti cars, Chanel clothes, etc.

        Build quality has diminishing returns. Rolexes and Bugattis are impressive feats of engineering, but I was aiming for the most utility per dollar, which would probably peak at a PCB, mechanical switches, group-buy dye-sub keycaps, and 3D printed cases. My evil plan would be to go on for other types of incredibly rare hardware that could run in emulation while the physical interface with the human can be replicated with reasonable accuracy with modern technology. A PC keyboard is not ideal for a Xerox Star, or a Symbolics, but is quite fine for an Amiga, Atari ST or Archimedes

When I was working on trying to update the CADR software, I found it helped to check in to a VCS all the versions of a particular source file over the previous version, what was your reason for going back to checking them in separately?
