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.

    Ted McCracken was my computer architecture instructor in maybe 2008. A few times in class he mentioned some of the startups he worked in the 1980s-90s, including Vectrix! He mentioned they built one of the first 3D megapixel video systems, and had to find(build?) displays that could do those resolutions as well, since everyone else was running around 320x240 or less back then. The early units were quite large, but eventually they fit it into XT/AT slots - I bet that's what you've got.

    If you don't mind, please take a picture of the card for Wikipedia before you sell it.

    How do you see any picture beyond the first one in an album?
    I don't see any obvious way with an ordinary web browser

    Finding all of these systems in a field of truck trailers and rusty school buses at my job is like a dream come true, I've finally used my first 286 system and get to semi-restore several of them.
    That's awesome Best of luck with the rest.

    If you're wondering about anything DG-related, drop a line to Bruce Ray at Wild Hare Computing (he's on the web). Bruce is the font of knowledge about anything from Data General.

    Welcome to the forums. For getting a handle on identifying boards, you usually need to provide hi-res pictures of said boards. Determining fair prices is usually done via searching SOLD ebay auctions (not active listings, and not unsold listings) and figuring out the average. You can ask here too, but collectors will generally quote you 50-70% of sold ebay prices due to no ebay fees.

    The Vectrix Pepe was intended as a secondary graphics adapter--you still needed an MDA or CGA for system use. In a way, it was a bit like the TIGA cards--drivers for only a set of mostly CAD programs--you needed a display compatible with the card as well. An IBM PGC predecessor.

    See under ISA for details. Vectrix was swallowed up by Everex sometime during the 1980s.

  • Vectrix Pepe Processor Card Rev. C EGA and other vintage cards.

    I work at a machine shop, which I will not disclose unless I end up listing in the for sale section some larger items which would require pick-up.

    My boss had no idea he was sitting on the motherlode of IBM and compatible systems, even some Data General mainframes with disk packs.
    I've taken up the task of running a company eBay page, but some items I just can't find pricing or function for.

    This card I've found has a stub article on Wikipedia, but I know its usage now. Does anyone know how I should go about getting drivers and testing this unit?
    Any insight into their worth?

    I've got a box of varied cards from this time period and nearby eras of computing sitting beside my desk, and about 12 IBM systems ranging from '82 to '92 out in a school bus waiting for cleaning and testing.
    Hoping this forum is friendly and that I can learn a lot from interacting here.
Working...
