1980 Terminal with Linux – TeleVideo 950
- blueflow 3y agoStill supported by the terminfo db! If you ever use that to access a linux machine, do an export TERM=tvi950 and your TUI apps should be fine. Unicode support not included, sadly. Edit: As shown in the video after minute 28
- mprovost 3y agoI would be surprised if anything has ever been removed from terminfo. Thomas Dickey is doing God's work.
- rwmj 3y agoI only hope / imagine he has a warehouse of green screen terminals!
- kragen 3y agoalso if you have tui apps that don't use terminfo, you can run them inside screen or i think tmux; screen uses terminfo to display the vt100 it emulates i found this useful with my adm3a emulator
- chasil 3y agoI have a real vt100 in my basement, not sure if it works. It would not be difficult to attach and run mgetty on the serial port.
- nubinetwork 3y agoMy arm boards have no GPU but do have a USB to serial adapter built in... Setting it up was as easy as editing inittab to disable the stock ttys and enabling ttyS0. (Systemd is a little more complex, but afaik it's the same except its unit files instead)
- blueflow 3y agoSome things i had to consider with my vt520: - Not all baud rates work reliably, the higher ones cause screen corruption probably due to clock drift - Flow control is required because the terminal is likely not fast enough to keep up with all output. Software flow control (XON/XOFF) can't be used with tmux because tmux is hard-coded to disable it - No support for unicode characters
- nubinetwork 3y agoOut of curiosity, how fast can you go? I think the default for my board is 115200, haven't tried going higher.
- blueflow 3y ago115200 is out of reach for 80ies hardware. I ended up picking 9600 as standard for my retro stuff because that's the highest the IBM PC supports.
- nubinetwork 3y agoMakes sense. Cheers

- coffeebeqn 3y agoWow ok I was expecting a emulator or a look-a-like app but this is a real beige computer from the 80s
- seabass-labrax 3y agoThis is the real thing, but the cool-retro-term software[1] is a fun 'poor-man's teletype' to emulate the aesthetic! [1]: https://github.com/Swordfish90/cool-retro-term https://github.com/Swordfish90/cool-retro-term
- kevin_thibedeau 3y agoYou can also run an emulated VT100 and VT220 in MAME. Couple that with shader effects to add scanlines and pincushion distortion and you get a passable facsimile.
- sprash 3y agoNot real enough. This has the original vt100 firmware ROM built in and executed by an 8080 emulator: https://github.com/larsbrinkhoff/terminal-simulator https://github.com/larsbrinkhoff/terminal-simulator
- whartung 3y agoTangentially related, this reminds me way back when I was learning with our new PET 2001 machines, how I wrote a routine that would print text out as "300 baud" (not that I actually knew what that was), but rather, "print text slowly" so that it would look like a "real computer".
- cricalix 3y agoI recommend checking out his other videos too - the series on the Hydro Thunder machines was good, complete with reverse engineering the disk layouts and raw data storage setup, with the software available on GitHub. He can usually be found on Twitch on a weekend, but is currently on a break to the end of the month due to running past his connection transfer limits (can't even pay for more data).
- tom_ 3y agoI've got a tvi910+. It looks cool. Check it out: https://deskthority.net/wiki/TeleVideo_910 https://deskthority.net/wiki/TeleVideo_910 (that's a 910, but the 910+ looks exactly the same) I switched it on in 2019. Probably its first run since the late 90s. It started up fine, but the screen was filled with junk - hmm, did it always do that? I tried to connect it up to my Mac using some dupont cable, but I couldn't get anything useful to happen. I triple checked the pinouts but I could easily have got them wrong. It had a 6502 in it, and what looked like an EPROM. I put "investigate possibility of plugging EPROM into BBC Micro, dump, disassemble, diagnose" on my todo list, and I put the terminal back in a cupboard. But both items are still where I left them.
- timthorn 3y agoI've got one too - the sound of typing on it is really evocative, and I managed to get a couple of spare keyboards that I keep meaning to hook to a USB HID interface.
