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.

    8bit Friendly ISA VGA cards

    [wiki="File:Oti_01.jpg"]200px|thumb|top|an example of a Video Card, in this case an Oak OTI037C[/wiki]

    Here's a place to list and document any 16-bit ISA VGA cards that work in 8-bit ISA slots.
    There are a few VGA cards that are manufactured as 16-bit ISA, but will function properly in an 8-bit ISA slot. Some cards may require a jumper change or other modifications to work in an 8-bit ISA slot. Please post any information you may have here.

    WARNING: Some 16-bit cards are advertised as being 8-bit compatible, but require a 286 or better CPU, i.e. designed for an 8-bit slot in an AT class computer.

    WARNING: Be aware of clone cards. So for example, just because the VGA card's main chip is labelled "Trident TVGA9000i" does not mean that the card is a Trident TVGA9000i. The card could be an ACME 1234, a card not made by Trident, but uses the Trident TVGA9000i chip, and has an on-board BIOS that requires a 286 or better CPU.

    ATI

    • VGA Wonder (autosense)
    • Mach-8 (JU1 to position 2/3)
    • Ultra (JU1 to position 2/3)

    Oak Technology

    • OTI037C
    • OTI067 (autosense)
    • OTI077

    Trident

    • TVGA 8800CS (one or more jumpers have to be changed, Information varies)
    • TVGA 8900C - auto detects 8 bit. Successfully tested on IBM PS/2 Model 30 8086.
    • TVGA 8900D - Manual [here] indicates compatibility with "486, 386, 286 and PC compatibles" and that jumpers need to be changed for 8-bit operation.
    • TVGA 8900CL - Jumper settings that work on a Zenith 4MHz 8088 are: J1=on, J2=off, J6=on, J7=on, J8=on, J10-->J9=off,on,on,on (left to right) Note that the card did not work on a generic turbo 8088 board.
    • TVGA 9000B - From archeocomp: For 8-bit operation, all three jumpers on J9 need to be on. archeocomp verified 8-bit operation in an XT.
    • TVGA 9000C - From Caluser2000: "Connected the jumpers to J9 then had to remove the one off J10(blue) towards the rear ... and it worked in the 8 bit slot on the 286."
    • TVGA 9000C MKII - From modem7: Second version of 9000C - Jumper settings for 8-bit operation in manual [here] - Works in an 8-bit slot in my IBM AT. Does not work in my IBM XT or in my XT clone.
    • TVGA 9000I - Manual [here] indicates compatibility with "486, 386, 286 and PC compatibles" and that jumpers need to be changed for 8-bit operation.

    In general Cirrus Logic CL-GD542x cards (including CL-GD5426) are not 8-bit ISA compatible. CL-GD522x cards normally use unlatched LA23-LA17 signals and BALE, and while it could be possible that LA19-LA17 can be substituted with latched SA19-SA17 address lines and LA23-LA20 simply grounded I never seen a card that does so.

      I am using 8-bit OAK 037C with an IBM 5150 PC and an LG flat screen. Pictures of the 8-bit OAK 037c and many other cards can be found at http://www.vgamuseum.info/index.php/...6-oak-oti-037c. Dig around on that site for other cards. Information can also be found at http://stason.org/TULARC/pc/graphics-cards/. The OAK 037C has 4 dip switches. Anyone know what they do?

          I see it's an *8-bit* card and this list is for *16-bit* cards that work in computers that only have 8-bit slots, e.g., PC or XT.

            Oh,whoops.I just followed the link. I thought it was just for any VGA cards that worked.

                Just tested this Western Digital Paradise VGA Plus in my spare 5150 board. I removed the V20 CPU and threw in the 8088 from my PCjr to ensure compatibility. I didn't touch the dip switches but it worked in a 286 machine too without any adjustment.

                  I've extensively used a Video 7 VGA 1024i (Headland Technologies based) and an MCT-VGA-16 (Paradise based) in 8-bit slots and with 8088s.

                    For those looking specifically for a card that is known to work in an IBM 5150, see also the list at [here].

                      I got a Paradise PVGA1A 8-bit ISA card, which works fine in my IBM PC/XT 5160 (and Commodore PC20-III, but that should be less surprising).

                        Hello,

                        I just tried an ATI MACH32 16 bit on my Tandy 1000 TX and it seems to work fine. In the past, I also had the occasion to try a Realtek RTG 3106 and it was also working fine as far as I can remember.

                          Any 8Bit or 16Bit VGA-Cards known that offer a Serial-, a PS/2 or a Busmouse-Connector?
                          (thoght about using it in the PC side of an A2000 with a Bridgeboard AA286)

                            Some ATi cards, such as the ATi VGA Wonder 16, have a bus mouse connector.

                              Pretty much any retail version of the VGA Wonder, Mach 8, Mach32, and Mach 64 DRAM had the bus mouse connector.
