Forum Rules and 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.


Rule 1: 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.


Rule 2: 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.



Rule 3: 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.


Rule 4: "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.

Rule 5: 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.

      So far I have dug out the pci to pcmcia adapter, and pcmcia usb card. I have installed it into a p166, using win98. Card seems to work great! Added note, the pci to pcmcia card I have supports 5v pci!!!!

      Now to just find dos drivers that support it. No luck so far with 365sl cardware drivers. Its a TI based chipset. If I recall correctly, some thinkpads shared the same pcmcia chipset...
      So until I can find the dos drivers, still at a standstill. On the other side, I found the drivers needed for the NEC chipset on the pcmcia to usb adapter. So once the dos drivers for the pci converter are located...

      16-Bit PCMCIA Cards supported
      32-bit Cardbus Cards supported
      5V at 1Amp typ. with fault protection
      3.3V at 1Amp typ. with fault protection
      PCI Universal 3.3V and 5V keyed PCI board
      Supports TypeI, II and III card sizes. Slot has ejector lever
      Uses industry standard 1410 or 1211 controller chip, proven on all classes of processor, chipset and motherboard manufacturer. Yenta compliant, PCI2.2 compliant, PC99 compliant. Supports sleep and suspend modes. Intel 82365 compatible register set
      Comes with device drivers for Windows95(osr2+), 98, 98SE, Millennium Edition, NT4, 2000, XP and Vista (32-bit) with support also for Linux and MacOS9 as standard. DOS driver also available on request
      Works with any card type thanks to patented driver
      Perfect for Wireless LAN, Bluetooth, GPS, GSM, GPRS cards etc
      Also works with Compact Flash, Memory Stick, SmartMedia, MMC and SD cards using suitable adapter available separately

        Atm , still stuck not having working drivers in dos. The manufacture claims to support dos so I sent them an email. Currently awaiting their response...

          maybe i'm nuts, but windows 2000 always seemed to be faster for me on 486 systems than windows 98 as long as you have at least 64 MB of RAM. it's most noticeable when doing some multitasking. after installing it, go in and disable unnecessary services and it will run pretty nicely.

          you might want to see how that works out. how much RAM is in the machine? windows 2000's USB support clearly puts 98's to shame.

            Mike, you're not nuts. The difference is especially noticeable on large partitions, where 98 is using FAT32 and NT is using NTFS.

              I think you are onto something here...

              I seem to recall ISA to PCMCIA adapters being fairly common place back in the day, so one could in theory could do ISA to PCMCIA to USB in a 486 system, I want to say in win95 (might be 3.x/NT4 im thinking) you needed some kind of "card services" software for PCMCIA, but I think 98, ME, and 2k would be do-able out of the box for PCMCIA.

              EDIT: I know this would be slow as ISA bus doesn't have bandwidth for USB, but should have enough for KB/Mouse and SLOW USB Flash drive access.

                Well I have tried a few times, and no luck yet. In win9x I get BSOD's trying to use any USB hid device or mass storage. The drivers do install, and the PCMCIA USB adapter is found and initialized. Everything posts functional in device manager... Till I plug something in! LOL!

                As for in dos, I cannot even get the PCMCIA card initialized. The drivers refuse to detect. Not giving up hope yet though...

                BTW keep in mind this is a PCI to PCMCIA adapter, not ISA. ISA will not work, its 16 bit. PCI supports 32 bit. USB PCMCIA cards require 32 bit Cardbus PCMCIA, unlike say wifi cards which do come in 16 bit flavors (eg Cisco 350/360 series). Now perhaps it may work with some sort of MCA/VLB/PCI SCSI to PCMCIA adapter...

                    BSOD before windows even loads...

                    I have a feeling the cardbus adapter I have doesnt support the IRQ/DMA required by the PCMCIA usb adapter. Guess I will have to look into it further when I have time. I do know now it functions properly however having managed to get a PCMCIA 10mb Flash Card working and formatted!

                      You should try an older USB 1.1 PCMCIA card, NOT a CardBus card, there is a difference, most ISA/PCMCIA bridge cards I have seen are not designed to handle cardbus.
                      EDIT: Main Difference PCMCIA = 16-bit, Cardbus = 32bit. ISA being a 16bit bus wont handle cardbus.

                          It could be a power problem. Most pcmcia to USB cards have a socket to plug in an optional power supply, the pcmcia socket doesn't have enough power to run something like a USB hard drive. That's also a lot of stuff daisy-chained off of a 486 slot. How many watts is the motherboard power supply good for?

                            I have seen them before, but they are not easy to find, I guarantee all the USB 2 ones will be cardbus, but USB 1.1 cards could go either way. Visually the connector edge of the cardbus cards is usually gold colored, and PCMCIA is usually silver, that makes it easier to tell when you cant trust the sellers ad.

                              No extra power socket. PSU is a 300W, more then ample for a p166 system. I really don't think its power. Guess I am stuck till I can locate another pcmcia usb card, and try again. I know i have another cardbus usb 2.0 card somewhere. I'll keep my eyes peeled for a usb 1.1 card...

                                What an interesting chain of developments here!
                                I don't have any PCMCIA adapters to test with, nor any of the required USB adapters, but the idea to even consider this would never have popped up for me if noone had mentioned it
