#vt320 — Public Fediverse posts

Taking a look at the 8051 code in an LK201 keyboard has been an interesting and educational diversion from the 8051 code in the #VT320 terminal that I’m _really_ interested in. For starters, almost everything about a keyboard is smaller – no external RAM, ROM, NVRAM or DUART, just the inbuilt serial buffer, 4K of code and 128 bytes of RAM. It has provided a way to improve my 8051 emulator from a collection of hacks for one purpose to a more reusable, hookable system. #retrocomputing

Now I can send key presses into the #VT320 emulation, I can explore set-up mode and save configurations to the nvram. This morning the terminal kept saying ‘NVR Error’ when I did that. Hmm, close examination revealed that I’d typo'd my implementation of the ER5911 SEEPROM and I’d swapped the opcodes for ‘Program Disable’ and ‘Erase All’ so I was not only erasing everything that’d just been saved, it took 20 ms to do that, when the nvram should’ve been ready immediately. Hurrah. #retrocomputing

It’s taken three weeks of effort to write emulators for the 8051 microcontroller, ER5911 SEEPROM, SCC2681 DUART and get frustrated over the timings required to make the firmware happy, but my #VT320 emulator now runs the original ROM far enough to pass POST. At this rate, I’ll have understood and annotated the rest of the code by its 40th birthday, and not a minute before. 😓 #retrocomputing

I’ve just started disassembling the ROM for Digital’s VT320 terminal, which contains an 8051. I'm using D52 to direct the disassembly. The 8051 has a 16-bit register DPTR, through which you can access either ROM or RAM, which are separate spaces, requiring two symbol tables. The documentation describes a directive "d" which can say, for each opcode address, which symbol table should be searched. Except ... it doesn't work. So, to fix D52 before the real job! #retrocomputing #VT100 #VT320

Sur la table d'opération un terminal #dec #digital #vt320 , le tube est un peu fatigué je reprends la procédure d'alignement de l'image pour voir si je peux un peu l'améliorer

Homelab update. #vt320

Inspired by this to style a Windows Terminal+PowerShell prompt like a VT320 term using your font and oh-my-posh.

Honestly I spent way too much time making it work, but it does look pretty cool.

The toolbar is an illusion, though - actually part of the prompt. I wish OMP had a way to "pin" a block at the top of the terminal.

(no I won't add the retro terminal effects in WT because it's ugly and annoying)

@MMWW Just stumbled across this LGR clip about the #VT320: https://www.youtube.com/watch?v=RuZUPpmXfT0

@DavittoKun @landley also we do it for #fun and maybe even #lulz to some degree:

I'm basically self-taught in regards to anything #IT and I think being humble about things is the way to go.

I did start OS/1337 asking myself "What is the simplest OS where I as a (#Linux & #Unix-esque only - cuz I don't do #Windows!) #Sysadmin could do my job under?" and turns out in therms what isn't "#BigIron" aka. somewhere remote, all I need is the modern incarnation of a #DEC-Style #Terminal like a #VT320 but with like #OpenSSH to get connected...

📸🕹️ The interactive exhibit that allows visitors to experience retro video terminals has received a new feature this week - sending photos from the Game Boy Camera to email. 😎

I’ve never done drugs but I have seen a #VT320 smooth scroll and that’s pretty much the same thing.

:fediverse: Now that there are so many people here, maybe there's a chance:

🖥️ In the 1990s, I used a #MicroVAX II with a #DEC #VT320 #terminal like the one shown here, but with an original black plastic case for both the monitor (white monochrome) and keyboard as sold new by the vendor (Evans & Sutherland).

🔎 Has anyone ever come across one of these with the black case? Surely some of these rare models were saved from the landfill.

My challenge to use my #vt320 as my main computer (besides phone) for all of September begins tomorrow!

Suggestions for a tag?

I will try to toot daily my #vt320 September experience!

All of September--only using a #vt320 (besides phone).

I'm challenging myself to use my #vt320 terminal as my main computer (excluding my phone) for all of September.

Should i write blog posts weekly? Or as one big post at the end of the month? Any ideas?

#simpleseptember: I'm going to use a #VT320 terminal as my primary computer for all of September. Development, entertainment, gaming, research, blogging, and more.

I will document my experience.

I will use my phone, still.

#lineart You can Access Everything #vt320

I have a rackmount server I administrate with a #vt320 terminal. Today I just built and installed my own DAS (basically an overglorified rackmount external HDD enclosure supporting many HDDs) using a spare rackmount server case (which I eventually want to replace in the future, because it's very unfriendly for installing and removing HDDs and cannot hold many).

I was inspired by this guide: https://www.serverbuilds.net/16-bay-das

So, I have been working on "PsychDOS" and finally uploaded some of the development logs and updated the docs section of the PsychDOS part of the site (with JS enabled, you can use your keyboard to navigate): https://psychoslinux.gitlab.io/DOS/INDEX.HTM. No screenshots yet. but there might be soon as I am pretty comfortable with the UI I have, or at least at the moment. #PsychOS #linux #dos #webdesign #vt320 #crt #retro #oldschool

I don't collect vintage tech... I merely accumulate #retrocomputing gear. It turns out I have 9 CRTs in my small retro room. And no Macs.

I think about two of them are CRT monitors (monochrome, naturally). One is a telly. Or maybe two. And one is an oscilloscope. One's a Minitel. One's an #amstrad #pcw ... there might be a #vectrex in there. There's a #vt320 somewhere too.

Oh, yes, and there is a colour CRT monitor too.

I haven't been doing much lately, but what I have done is hook up my #vt320 to my #debian server so I can use it as a programming, IRC, and more device! I'll send a video and some pics soon.
