Ohhhhhh man! I've been on the hunt for a VT-220 for a while! As a fifth grader, I audited a Fortran 77 class in 1992, and the lab was full of these connecting to a VAX! Soooo many memories! I haven't found one in reasonable shape for a reasonable price though yet :(
What's funny about those DEC terminals is that the monitors improved with newer models but the keyboards became worse (the keyboards shipped with the VT420 were terrible - so flimsy and light). As such, I used a VT220 keyboard with a VT420 monitor!
Why did you keep calling Navy commercials Army? I was in the Navy and it is not even close.
Hello Adrian: As usual a great video. Hayes AT commands reference is a must have for any serial device. ATDT is AT = Attention D=dial T=touchtone. Ran a BBS back in the day. Got real familiar with modem commands and the AT subset. Thanks for the great video.
This is the second video where I think you are introducing a weird variable by using xt ide. just boot from a floppy. the less weird stuff you have when you do the tests, the better.
A little knowledge is a very dangerous thing.
I had a DEC rainbow 100 that used CPM 86/80
I had a VT220 just like that, although I think my keyboard was a little different. My dad picked it up at a military surplus place around '95 or so, and I used it as a terminal for my Linux PC so my brother and I could both use it at the same time. I kept it for a long time, but did eventually get rid of it.
I have a G3 card in my 7600/120 Mac Power PC, that looks similar to that board. However, the upgrade card I have, is made by Sonnet, who made a lot of upgrade stuff for the Power PCs. I bought the the 7600 as a used computer, and even after doing several upgrades on the machine, I just wasn't happy with the performance. So, now it sits in my basement, unloved. They also sold a G4 upgrade, but it was expensive, and I was so underwhelmed by the performance, that I never bothered with any further upgrades. For awhile, I was thinking about putting Linux on it.
14:37 The CPC 6128 was exported to the US and Latin America by Indescomp S.A., a Spanish company that produced Amstrad, MSX, Amiga and Spectrum games and made NTSC conversion of the machine, it was somewhat popular in South America, but MSX and Amiga were way more popular on here.
This takes me back, I was DEC VMS administrator that supported All-IN-1 which was an singular interface for mail, Wordperfect, and Lotus 123. Most of the VT terminals I dealt with used MMJ connectors for their serial connection that are like RJ-45 but the locking tail is offset to one side.
Fun fact about this east german DIL packages.. they have a metric 2.50mm pin pitch, not 2.54mm (0.1"). Doesn't matter much for 14 or 16pin, but for a 40pin the last pin is 0.8mm off, meaning they won't fit into western precision sockets. Learned that the hard way.
p=pulse, t=tone
I liked "The Specialist" (James Woods stole the show) and even "The Puppet Masters", mostly because of Julie Warner, who had that rare talent of exuding innocence and sexiness at the same time. Only two other actresses, to my mind, had that gift: Gillian Anderson and Kate Winslet.
Your flash-light doesn't flash.
Where can I get one of those serial -> wifi modems? I have some old Psion palmtops I would love to get online.
Cela me rappelle mes cours de programmation en Fortran, connecté à un VAX-11/VMS ;-) This reminds me of my Fortran programming lessons, connected to a VAX-11/VMS ;-)
The problem I had with getting the COM [n] to get through the pico was using a USB micro with power AND data capabilities. Apparently the cheap ones from the corner store only charge devices!
I love these retro videos!! ATDT brings back memories of 1986 when I had to dial the phone to hook up by modem to the mainframe at UC Berkeley on my Apple Iic (and later Mac) with a terminal emulation program. I liked going to Evans Hall on campus to use the terminals hard wired to the mainframe, or it seemed like it since it was so much faster than 1200 bps over phone lines.
I have a white-screened one in my basement that AFAIK was used for secret government projects. Rather than using a Wi-Fi modem I was thinking of connecting it to the console port of my managed network switch and using the switch's telnet client functionality. The VT220 should be easier to use than my HP Palmtop.
nice fix, maybe the ferrite rod is intentionally bent in order to have close clearance room for the back side.
Can you tell me more about the ESP32 serial modem you used. I use a Raspberry Pi Zero/TTL>RS232 board to do a similar job. But I have a bunch of ESP32s lying around. Thanks.
I love amber displays. They are my fav. I dont like white or green ones.
but you can not use lightguns with lcd
Pretty sure there was no way to change backspace from the terminal. Step one after connection was always hit the backspace to test and then a: stty erase ^H
Yeah, amber OFTEN has burn-in. :( Sucks, 'cause I have the most nostalgia for amber screens, since my first computer had one.
Eeeyyy it's the terminal software that inspired the Unified Operating System we see in Fallout's terminals!
Wordperfect on a VAX? Something new to learn every day (and showing I’m definitely PC age, although uni did have a VAX - but no WP!)
Did you know? "warranty void if removed" stickers are illegal.
This is a really cool terminal. We had the same or similar ones in our local library. Not sure when they started using them, but I used them in the mid-late 90's and maybe early 00's. They used it for their card catalog as well as looking up which other local libraries had certain books. I think you could even reserve books through the system! So yea, I have a strange bit of nostalgia for these machines. I know they had amber terminals, but I think some of them might have been green as well.
ATDT means ATtention Dial Tone. ATDP is ATtention Dial Pulse Nothing to do with character sets.
Started my career working on one of these, identical to that coding in VAX Basic and C on VAX's, and Micro VAX's. DECs machines and the VAX/VMS OS were amazing back then - so well designed.
I used to work at a company that produced medical software . At customer sites, they actually had monochrome LCD monitors that were used in radiological contexts.
Late 80s they had the 320 and by early 90s the 420. I have both.
We had a room full of these in college back in 1991, attached to an IBM RS6000, if I remember correctly. The IBM machine would frequently crash, and the background noise of typing would slowly die down as people realized they were getting no responses, followed by the inevitable heads popping up to see if everyone else was stuck. Happy days.
ATARI 1200XL = Fantastic computer!
Yes, the KC85/3 was rather expensive, about 3900 east german mark, when an average monthly salary was at 800-1000 mark! Go figure!
Can the software also give signal instructions or is it just for image calibration?
Got a green wy-30 older than the vt standard
Backspace isn't working for me either on a modern machine running Arch and st. This BBS is set up so it only accepts ^h.
There is no key labeled ESC on the VT220, but in VT100 mode the F11 key functions as one. The VT220 terminal was clearly designed for the VAX/VMS era, since on the earlier DEC-20/TOPS-20 the escape key was extensively used. The Wikipedia VT220 article has a separate paragraph titled the "Escape key controversy".
One of the classic terminals. Used one for many years as a sysadmin - I think I was one of the last with a terminal on my desk (before it headed home). The VT220Z was even better as it had 4 pages of memory so you could scroll back through the text that had disappeared off the screen.
Digital Equipment Corporation, not Digital Electronics Corporation - That looks like it was from a Word Processing System (WPS) - pronounced "WOOPS". These were PDP 11/23 or MicroVax machines that would sit under the desk. The PF1 key was called the "gold key" which put the keypad in the second state. What distinguishes the keyboard is the labels on the keys, with the "red" and "green" keys inserting fonts, styles, and formatting. You had WPS as part of the AllIn1 suite on the VAX, so the key assignments matched the stand alone machine. The WPS terminal was a VT220, but wouldn't have the VT220 badge on the front. I still have the muscle memory for the EDT keypad and can move and edit a file faster than I can in vim. Cool thing I learned when I was going to SUNY at Buffalo back in the mid 80's was definineing the keypad to execute funtions in DCL. So, when at the command line, I had a key defined to "show default" and other functions. Cool stuff.
Yes, same here. I too have muscle memory of the EDT and LSE keypads. Gotta love "learn keys" in LSE. Another thing I used to do was put my username in the answerback, so that I could log in quicker.
are MMJ crimps and jacks that uncommon? I got a set decades ago when I still had a bunch of DEC gear, so I could make MMJ to DB9 adapters for serial consoles. I gave away most of my DEC gear, but still have the kit to crimp new cables.
