Hello all, I've recently been improving the AT&T/Teletype DMD 5620 simulator I wrote a few years ago. It can now run either the 8;7;3 or 8;7;5 firmware. It also now supports executing a local shell or connecting directly to a physical or virtual tty device. It runs natively on Linux or macOS with X11 or Wayland, but I would love help creating a Windows version if you're a Windows programmer (I am an occasional Windows user, but I am not at all knowledgeable about Windows programming). Full details are available here: https://loomcom.com/3b2/dmd5620_emulator.html The source code is here: https://github.com/sethm/dmd_gtk Many thanks go to my friend Sark (@crtdude on Twitter) for tracking down the 8;7;3 firmware and dumping it for me. I'd also like to thank Mike Haertel for helping find bugs, providing feedback, and inspiring me to get it working with Research Unix in addition to SVR3. Feedback, bug reports, and pull requests are all welcome! -Seth -- Seth Morabito Poulsbo, WA web(a)loomcom.com

Some time ago, Greg Christie, then at Apple, booted up a 3B2 with a 5620 attached and invited me to play with it. Now _that_ was a trip down memory lane. (The 3B2, maybe not so much.) It was a reward for an interview with him, recorded on video, about the early days of 2d graphics as I saw them, for a course for employees. But being Apple, even though it was 0% proprietary, it will never see the light of day. -rob On Tue, Sep 13, 2022 at 11:53 AM Larry McVoy <lm(a)mcvoy.com> wrote: > This looks like some really nice work.

I had a 3B1, very different machine, 68K based, I liked it.

I was wondering why you???d pick this term of all historical terms to emulate. Now I have a terrible urge to try my hand at an ADM-3A.

I wish we had found a consistent way to manage the client/server (or as we called it, terminal/host) separation. Every program did it a different way, with varying levels of success. We didn't push hard enough on it at the time, but Plan 9 came about in part by thinking about the problem, and to be honest so did JavaScript. -rob On Tue, Sep 13, 2022 at 11:01 PM Clem Cole <clemc(a)ccc.com> wrote: > > > On Mon, Sep 12, 2022 at 10:12 PM Larry McVoy <lm(a)mcvoy.com> wrote: > >> I have very fond memories of the BLIT terminals, I just liked how much >> you got out of a serial cable.

I was wondering why you’d pick this term of all historical terms to emulate. Now I have a terrible urge to try my hand at an ADM-3A.

I haven’t. I’m not sure how much it differs from the acme experience, but I still miss them especially the terminal-as-editor. I hear some of the same people may have been involved. Which is why I can’t possibly make time for the adm-3a, that never ending hobby project is already claimed by my desire for acme with syntax highlighting. /me goes back to working in a :term inside neovim inside tmux inside a mosh session inside a glorified vt100 emulator, while absolutely not crying about applications being ignorant of presentation layer for “portability”
