Forum etiquette

Our mission ...

This forum is part of our mission to promote the preservation of vintage computers through education and outreach. (In real life we also run events and have a museum.) We encourage you to join us, participate, share your knowledge, and enjoy.

This forum has been around in this format for over 15 years. These rules and guidelines help us maintain a healthy and active community, and we moderate the forum to keep things on track. Please familiarize yourself with these rules and guidelines.

Remain civil and respectful

There are several hundred people who actively participate here. People come from all different backgrounds and will have different ways of seeing things. You will not agree with everything you read here. Back-and-forth discussions are fine but do not cross the line into rude or disrespectful behavior.

Conduct yourself as you would at any other place where people come together in person to discuss their hobby. If you wouldn't say something to somebody in person, then you probably should not be writing it here.

This should be obvious but, just in case: profanity, threats, slurs against any group (sexual, racial, gender, etc.) will not be tolerated.

Stay close to the original topic being discussed
  • If you are starting a new thread choose a reasonable sub-forum to start your thread. (If you choose incorrectly don't worry, we can fix that.)
  • If you are responding to a thread, stay on topic - the original poster was trying to achieve something. You can always start a new thread instead of potentially "hijacking" an existing thread.

Contribute something meaningful

To put things in engineering terms, we value a high signal to noise ratio. Coming here should not be a waste of time.
  • This is not a chat room. If you are taking less than 30 seconds to make a post then you are probably doing something wrong. A post should be on topic, clear, and contribute something meaningful to the discussion. If people read your posts and feel that their time as been wasted, they will stop reading your posts. Worse yet, they will stop visiting and we'll lose their experience and contributions.
  • Do not bump threads.
  • Do not "necro-post" unless you are following up to a specific person on a specific thread. And even then, that person may have moved on. Just start a new thread for your related topic.
  • Use the Private Message system for posts that are targeted at a specific person.

"PM Sent!" messages (or, how to use the Private Message system)

This forum has a private message feature that we want people to use for messages that are not of general interest to other members.

In short, if you are going to reply to a thread and that reply is targeted to a specific individual and not of interest to anybody else (either now or in the future) then send a private message instead.

Here are some obvious examples of when you should not reply to a thread and use the PM system instead:
  • "PM Sent!": Do not tell the rest of us that you sent a PM ... the forum software will tell the other person that they have a PM waiting.
  • "How much is shipping to ....": This is a very specific and directed question that is not of interest to anybody else.

Why do we have this policy? Sending a "PM Sent!" type message basically wastes everybody else's time by making them having to scroll past a post in a thread that looks to be updated, when the update is not meaningful. And the person you are sending the PM to will be notified by the forum software that they have a message waiting for them. Look up at the top near the right edge where it says 'Notifications' ... if you have a PM waiting, it will tell you there.

Copyright and other legal issues

We are here to discuss vintage computing, so discussing software, books, and other intellectual property that is on-topic is fine. We don't want people using these forums to discuss or enable copyright violations or other things that are against the law; whether you agree with the law or not is irrelevant. Do not use our resources for something that is legally or morally questionable.

Our discussions here generally fall under "fair use." Telling people how to pirate a software title is an example of something that is not allowable here.

Reporting problematic posts

If you see spam, a wildly off-topic post, or something abusive or illegal please report the thread by clicking on the "Report Post" icon. (It looks like an exclamation point in a triangle and it is available under every post.) This send a notification to all of the moderators, so somebody will see it and deal with it.

If you are unsure you may consider sending a private message to a moderator instead.

New user moderation

New users are directly moderated so that we can weed spammers out early. This means that for your first 10 posts you will have some delay before they are seen. We understand this can be disruptive to the flow of conversation and we try to keep up with our new user moderation duties to avoid undue inconvenience. Please do not make duplicate posts, extra posts to bump your post count, or ask the moderators to expedite this process; 10 moderated posts will go by quickly.

New users also have a smaller personal message inbox limit and are rate limited when sending PMs to other users.

Other suggestions
  • Use Google, books, or other definitive sources. There is a lot of information out there.
  • Don't make people guess at what you are trying to say; we are not mind readers. Be clear and concise.
  • Spelling and grammar are not rated, but they do make a post easier to read.

Bunker-Ramo Telequote III

    Yup, that display is what I remember. Very sparse, with roughly-formed characters.

    B-R Telequote, however, was not the first into the business of delivering stock market data electronically via a terminal. That distinction goes to Quotron (started in 1960). An early Quotron terminal would probably fetch a pretty penny today.

    B-R Telequote is most notable for being involved in squabbles with the FCC, SEC and various taxing entities. A lot of caselaw was determined back then.

      There was another dispute between Western Union and B-R over the Telequote IV which was going to allow messaging between terminals. That turned into the NASDAQ, but not before WU refused to lease lines to B-R claiming that such a switching service was in direct violation of their service agreement and was not permitted.

      B-R complained to the FCC, which decided in favor of B-R, and that decision was used (in part) to justify the FCC's recent net neutrality policies.

      Also, you are correct about Scantlin being first in 1962 to get quotes from the NYSE to brokers via a centralized CDC 160A. However those machines used paper tape, and maybe some nixie tubes. B-R was the first with a CRT.

        I actually worked on the telequote 1,2 and 3 in the 70's. The terminal is not going to do much other than display a green or orange (depends on the model) roster unless you get your hands on the controler.

          You are correct that its a dumb terminal that used to connect back to the Trumbull, CT data center via leased Western Union lines. I do have the schematics/manual, but they are under some heavy books for a few weeks to de-curl them. I guess, first I need to recap the thing. The 3" green phosphorus CRT doesn't work - hopefully recapping it will fix that. Then I want to figure out the messaging format and attempt to hook up the AM/P connector to a Raspberry Pi and then the Pi to Bloomberg in order to pull in live quotes. I will need help identifying parts suitable for replacement, tips on getting the ancient CRT back on if recapping doesn't work, and thoughts on how to decrypt the ancient messaging format and pinouts to bring her back to life with live quotes.
          The whole system was propriatary and will be all but impossible to hookup to Bloomberg or any other system. The terminal you have is nothing but a CRT without any control logic, and a keyboard. It attaches to a office controller called an RQT, which supported 3 to 29 terminals depending on the model. In turn, the RQT attached to a multi-drop 1200BPS line that was shared with as many as 10 RQT. This 1200BPS line was attached to a hardwired computer system which had as many as 28 lines. This computer, of which there were 13 scattered around the USA were updated by a central site system which was at first located in NYC and later in Trumbull CT

          But back to the terminal. The CRT had a unique saw tooth raster In the standard mode there were 4 lines of 6 characters. In the Trends mode there were 11 lines of 24 characters. The saw tooth raster had 6 lines and supported a 5 x 7 matrix plus a single space. Characters were formed from the lower left to the upper right plus a single line which spaced characters.

          The keyboard was scanned by the RQT roughly every 20ms. If a key was depressed it placed a 6 bit code on the keyboard bus. Although I designed 2 of the 4 versions of the RQT I don't recall the timing or the format of the signal that controlled the CRT. Nor do I recall the CRT drive circuitry.

          Good luck if you really try to get this working. The terminal is but a small part of the overall system.


            The office controller which supported the terminal was solid state, not vacuum tube. Three models of the office controller, known as RQT, were discrete transistor, the last version was TTL. I designed 2 of the 4 models.
